Write the point slope form of the equation of the line through the given points: (-4,-1) and (-3,1)
PLEASE EXPLAIN. STEP BY STEP INSTRUCTIONS
Answers
Step-by-step explanation:
the general point-slope form is
y - y1 = m(x - x1)
with (x1, y1) being a point on the line, and m being the slope (the incline of the line).
we have the point. we can pick one from the 2 choices, I typical go for the one with smaller values. so, I will use (-3, 1).
now we need to calculate the slope.
the slope is the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, for our 2 points we see
x changes by +1 (from -4 to -3).
y changes by +2 (from -1 to +1).
and the slope is +2/+1 = 2
therefore our equation is
y - 1 = 2(x - -3)
or simplified
y - 1 = 2(x + 3)

What is the equation of the line????????
Answers
Answer:
y=1/2x+2
Step-by-step explanation:
The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.
To find the gradient is a little more tricky, but we can follow the formula:
[tex]\frac{rise}{run}[/tex], where rise is the vertical value and run is the horizontal value
So we sub in our values:
[tex]\frac{2}{4}[/tex]
And simplify:
[tex]\frac{1}{2}[/tex]
So now we sub in our new found values into y=mx+c:
y=1/2x+2
Answer: y = x/2 + 2 which is the 4th option from the top
Step-by-step explanation:
First find the slope which is (0-2)/(-4-0) = 2/4 = 1/2
So it's y = x/2 + c
Substituing (-4,0) into the equation we get
0 = -4/2 + c
0 = c-2
c = 2
So the equation is y = x/2 + 2 which is the 4th option from the top

For number eight, you have to multiply out by 2. For example,
9 x 2= 18
2 x 2= 4
7 x 2= 14
For number ten, you have to subtract by 9. For example,
51 - 42= 9
10 - ___= 9
the space would be 1 because 10-1 equals 9
For number 12, you have to multiply out by 9
5 x 9=45
10 x 9= 90
9 x9= 81

An article was sold for ₹250 with a profit of 5%. What was its cost price?
Answers
Answer:
Selling Price 250
Profit =5%
We are given to find the cost price of articles .
First we find the profit
► Profit = 250/100 × 5
► Profit = 2.5×5
► Profit = 12.5
Cost Price = Selling Price - Profit► Cost Price = 250-12.5
► Cost Price = 237.5
So, the cost price of the article is 237.5
Selling price of the article.
Profit percentage %.
To do:
We have to find the cost price.
Solution:
Let the cost price of the article be .
Profitpercent = SP-CP/CP × 100
5 = 250-x/x x 100
5x = (250-x) 100
x = (250-20) 20
x = 250 (20) - 20x
x + 20x = 5000
21x = 5000
x = 5000/21
x = 238
Therefore; cost price of the article is Rs 238

Your total after 4 games of bowling was $28
and after 6 games it was $40. What was the
initial cost to rent the shoes before bowling
any games?
Answers
Answer:
$4
Step-by-step explanation:
Let x be the cost of a game of bowling and y be the cost to rent the shoes before the game then...
4x+y=28
6x+y=40
We can solve this system using elimination. In this scenario, we can eliminate y by subtracting the two equations...
-2x=-12
Divide both sides by -2
x=6
Plug 6 back in for x to solve for y
4(6)+y=28
24+y=28
Subtract 24 from both sides
y=4
It costs $4 to rent the shoes before bowling
