Answer:
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
Find the slope
Take two points from the graph
(0,3) and (4,4)
The formula to calculate the slope between two points is equal to
substitute
The y-intercept is the point (0,3)
so
substitute
January: 32
February: 28

Equation of a line is in the form y = mx+c, where m is the gradient and c is the y-intercept.
First step is to find the gradient.
m = (y2-y1)/(x2-x1)
= ( 5- -8)/(8-4) = 13/4
We have y = (13/4)x + c
Now we replace one of the coordinates to find c. Let’s replace (4,-8)
We have: -8 = (13/4)*4 + c
-8=13+c
c=-8-13= -21
Therefore, equation of line is:
y = (13/4)x - 21
The formula of a slope:
We have the points A(-6, 6) and B(12, 3). Substitute:
Therefore we have 
.
Put the coordinates of the point B to the equation:
<em>add 2 to both sides</em>
