You can put this solution on YOUR website!
First, you can identify the y-intercept.
(0,-4)
Then find the slope by counting change in y over change in x.
Looks like (6,5) is another point on the line.
m=%285-%28-4%29%29%2F%286-0%29=9%2F6=3%2F2
So,
y=%283%2F2%29x-4

you just need the coordinates of two points that lie one line to find the equation of that line
y=mx%2Bb
use y-intercept which is at (0,-4)
so, we already know b: b=-4
y=mx-4
to find a slope, use (0,-4) and the point (4,2) which also lie on a line
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29=%282-%28-4%29%29%2F%284-0%29=6%2F4=3%2F2
then, your equation is:
y=%283%2F2%29x-4
