Y=m x + b is the form where m is the slope, and b is the y intercept.
to get from the y intercept (-2) to the x intercept (+5) You have a rise of 2 and a run of 5
Therefore
y = 2/5x -2

The equation for a line is y = mx + b, m being the slope and b being the y intercept. First you want to verify the slope. you've the factors (0,-2) and (5,0). Slope is the change in y over the change in x. Y went from 0 to -2 and x replaced from 5 to 0. for this reason your slope is two/5. Now you position each of the assistance you be conscious of into the equation y=mx+b. -2= (2/5)(5) + b -2=2 + b -4=b so, your equation is y=2/5x - 4.

(5,0) and (0,-2)
m = (y2-y1)/(x2-x1)
m = (-2 - 0) / (0 - 5)
m = -2/-5 = 2/5
y = mx + b
-2 = 2/5(0) + b
b = -2
y = 2/5x -2
