Find the equation of the line in tandard form that pae through the point (1, -3) and (-2, -1)
The equation of line in standard form that pass through the point (1, -3) and (-2, -1) is (-2x/3)-y=7/3 where -2/3 is x-intercept and -1 is the y-intercept.
What does the straight line equation mean?A straight line's equation is given by y=mx+c, where c is the height at which the line intersects the y-axis (often referred to as the y-intercept) and m is the gradient.
Why is there an equation of a line?The set of points that make up a line in a coordinate system are represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y.
we are given with;
x1=1, y1=-3
x2=-2, y2=-1
equation of line in standard form:
Ax+By=C
so using formula:
(y−y1)=(y2−y1)(x−x1)/(x2−x1)
(y−(-3))=((-1)−(-3))(x-1)/(-2−1)
(y+3)=(2)(x−1)/(-3)
(y+3)=(2x−2)/(-3)
y+3=(-2x/3)+(2/3)
y=(-2x/3)+(2/3)-3
y=(-2x+2-9)/3
y=(-2x-7)/3
(2x/3)+y=-7/3
rearranging;
(-2x/3)-y=7/3
This is our required answer.

what is the slope of the line?
The slope of the graph of the line is 40.
What is slope?The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.
Taking any to points on the line point (5, 200) and (10, 400)
Slope = change in y-coordinates / change in x-coordinates
change in y-coordinate = 400 - 200 which is 200
change in x-coordinate = 10 - 5 = 5
slope = 200/5 which is 40

As per the unitary method, the number of tulip were 21.
Unitary method:
In algebra, unitary method defines how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.
Given,
Here we have There were 35 bunches of rose and tulip. Each bunch had 12 of the roe flower. There 7 more bunches of tulip than rose.
Now we need to find how many tulip were there.
Let number of bunches of roses be x.
And then the number of bunches of tulips will be x + 7
The total number of bunches of flowers = 35
So, it can be written as,
=> x + x + 7 = 35
When we simplify this one then we get,
=> 2x + 7 = 35
Now, we have to subtracting both sides by 7
=> 2x = 28
Then dividing both sides by 2
=> x = 14
So, the number of bunches of roses = 14
Then the number of bunches of tulips = 14 + 7 = 21

In a company, 80% of the workers are women. If 760 people work for the company who aren't women, how many workers are there in all? Use pencil and paper. Show two different ways that you can solve this problem.
Using mathematical operations, we know that the total number of workers in the company is 3,800.
What are mathematical operations?A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.
There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.
Parentheses, Exponents, Multiplication, Division, and Addition Subtraction are also known as PEMDAS (from left to right).
So, we know that 80% of all workers are women.
760 people who work for the company are not women.
Which means:
80% = x
20% = 760
Now, calculate the total workers as follows:
80/x = 20/760
20x = 80 * 760
x = 80 * 760/20
x = 3,040 (Women workers)
Total workers: 3040 + 760 = 3,800 workers
Therefore, using mathematical operations, we know that the total number of workers in the company is 3,800.

Emma grew 6 plants with 3 seed packets. How many seed packets does Emma need to have a total of 16 plants in her backyard? Solve using unit rates.
8 seed packets
Step-by-step explanation:First, we need to figure out how many plants Emma can grow with each seed packet. To do this, divide 6 plants (the number of plants Emma currently has) by 3 seed packets (the number Emma had to begin with). This will give us a unit rate of "2 plants per seed packet".
Now that we know the unit rate, we can use it to figure out how many seed packets Emma needs to have 16 plants in her backyard. Divide 16 plants (the number of plants Emma wants to have) by 2 plants per seed packet (the unit rate). This will give us 8 seed packets.
Therefore, Emma needs 8 seed packets to have a total of 16 plants in her backyard.

The solution of the system of equations is (x, y) = (9/2, -7/10).
What is the system of linear equations?
A system of linear equations is a group of one or more linear equations that can be solved by using a simultaneous equation or elimination method. Therefore, by using the substitution method and writing the solution of the system in terms of coordinate point (x, y) = (-1, 1).
To solve a system of equations, we can use any of the following methods:
Substitution method,
Elimination method,
Matrix method.
Let's use the substitution method to solve the given system of equations.
We can solve the first equation for z:
z = 7 - 3x - 2y
Substituting this expression into the third equation, we get:
3x + 2y + 3(7 - 3x - 2y) = 1
This simplifies to:
-5x - 3y + 21 = 1
Adding 5x and 3y to both sides, we get:
21 = 5x + 3y + 1
Subtracting 1 from both sides, we get:
20 = 5x + 3y
Dividing both sides by 5, we get:
4 = x + 3/5 y
Substituting this expression into the first equation, we get:
3(x + 3/5 y) + 2y + 7 = 7
This simplifies to:
2y = -7/5
Dividing both sides by 2, we get:
y = -7/10
Substituting this value into the expression for x, we get:
x = 4 - 3/5(-7/10)
This simplifies to:
x = 4 + 21/10
x = 9/2
Hence, the solution of the system of equations is (x, y) = (9/2, -7/10).
