Equation of the line in slope-intercept form = y = 8x − 1
How to calculate the equation of the line?
Given:
Co-ordinates of the first line (x, y)=(0,-1), (1,7), (2,15), (3,23),(4,31)
We know that,
[tex]\text{slope }=m=\frac{y_2-y_1}{x_2-x_1}\\\\= > \frac{7+1}{1-0}\\\\=8[/tex]
The slope - intercept form of a line is given by,
y = mx + b ---(1)
Let us substitute ( x, y )= (0, -1) in (1)
-1 =(8)*0+b
-1= b
b = - 1 ----(2)
Let us substitute m and b in the slope-intercept equation (1)
y = 8x − 1

Which of the following equations describes the line shown below? Check allthat apply.(-5,6)(-1,-1)
Answers
Options E and F are the correct options
Here, we need to get the equation of the line that passes through the two points given
Mathematically, the equation of a line can be generally expressed as ;
y = mx + c
where m is the slope of the line and c is the y-intercept of the lien ( where it crosses the y-axis)
To get the slope m , we are goint to use the formula below;
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_{2\text{ - }}x_1} \\ \\ x_{1\text{ }}=-5,x_2=-1,y_1\text{ = }6,y_2\text{ = -1} \end{gathered}[/tex]Substituting these values into the slope equation , we have
m = (-1-(6))/(-1-(-5)) = -7/4
The equation is now in the form;
y = -7x/4 + c
what is left is to get the y-intercept
We can get the value of the y-intercept by substituting for x and y using any of the points
Let us use the second point
Here, x = -1 and y = -1
Thus;
-1 = -7(-1)/4 + c
-1 = 7/4 + c
c = -1-7/4 = -11/4
So the complete equation of the line is;
y = -7x/4 - 11/4
To properly answer the questions, we need the forms in the options that looks like or can be manipulated arithmetically to look like what we have as our answer
We proceed with each of the options one after the other to see if they can be written in the form of our answer
Option A
y - 5 = -7/4 ( x + 6)
Opening the bracket and evaluating;
y - 5 = -7x/4 - 42/4
y = -7x/4 -42/4 + 5
y = -7x/4 -22/4
we can see this is not a correct option
Option B
y - 6 = -4/7 (x + 5)
Multiply through by 7
7y - 42 = -4x - 20
7y = -4x - 20 + 42
7y = -4x + 22
divide through by 7
y = -4x/7 + 22/7
We can see this is incorrect also
Option C
y - 1 = -4/7(x-1)
Multiply through by 7
7y - 7 = -4x + 4
7y = -4x + 4 + 7
7y = -4x + 11
divide through by 7
y = -4x/7 + 11/7
This is incorrect too
Option D
y + 1 = -4/7 ( x + 1)
Multiply through by 7
7y + 7 = -4x - 4
7y = -4x -4 -7
7y = -4x - 11
y = -4x/7 - 11/7
This is incorrect also
Option E
y - 6 = -7/4 (x + 5)
Multiply through by 4
4y - 24 = -7x - 35
4y = -7x - 35 + 24
4y = -7x -11
y = -7x/4 - 11/4
This is a correct option
Option F
y + 1 = -7/4 ( x + 1)
Multiply through by 4
4y + 4 = -7x - 7
4y = -7x - 7-4
4y = -7x - 11
y = -7x/4 - 11/4
This is a correct option too

The angles in the parallelogram is as follows:
a = 27°b = 55°c = 55°How to find angles in a parallelogram?A parallelogram is a quadrilateral with opposite sides equal to each other and opposite side parallel to each other.
The diagonal of a parallelogram bisect each other.
Therefore, the angles a, b and c in the parallelogram can be found as follows:
180 - 118 - 35 = a (sum of angles in a triangle)
180 - 153 = a
a = 27 degrees.
Therefore, let's find angle b.
62 + 63 + b = 180 (sum of angles in a triangle)
125 + b = 180
180 - 125 = b
b = 55 degrees
Let's find the angle c
Hence,
b = c (alternate angles)

[tex]\begin{gathered} \angle BAD\cong\angle ABC \\ \angle ADC\cong\angle BCD \end{gathered}[/tex]The angles are congruent because if AD and BC are congruent, and the lines are parallel, they sides will form the same angles.
Also, as the segment AD is "cut" by two parallel lines, the angles BAD and ADC are consecutive interior angles and are, therefore, supplementary.

So,
Suppose the two points are:
[tex](1,\text{ 5) and (}3,\text{ 3)}[/tex]Now,
From the formula of slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where,
[tex]x_1=1,y_1=5,x_2=3,y_2=3[/tex]Put all the above value into the given formula
So,
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{3_{}-5_{}}{3_{}-1_{}} \\ m=-\frac{2}{2} \\ m=-1 \end{gathered}[/tex]Hence, the value of the slope is -1.
Now,
For the equation of the line that is based on the given chart, use two supposes point and the given slope.
So,
The two poin and slope is:
[tex](1,\text{ 5) and (3, 3) and m=-1}[/tex]Then,
From the formula of two point form;
[tex](y-y_1)=m(x-x_1)[/tex]Where,
[tex]x_1=1,y_1=5,x_2=3,y_2=3,\text{ m=-1}[/tex]Then,
Put all the given value into the above formula
So,
[tex]\begin{gathered} (y-y_1)=m(x-x_1) \\ (y-5_{})=-1(x-1_{}) \\ (y-5)=-x+1 \\ y-5+x-1=0 \\ y+x-6=0 \end{gathered}[/tex]Hence, the equation of the line is:
[tex]y=-x+6[/tex]Now,
To find the y-intercept, put x=0 and solve for x
So,
The y intercept of the given equation is:
