Answer:

y = -1/5x - 10

Explanation:

Pick any two points on the line.

(0,-10) and (50,-20)

find the slope by using m = y2-y1/x2 - x1(rise over run)

m = -20-(-10) / 50 - 0

m = -10/50 = -1/5 -- this is your slope

slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.

so now you have all the points you need.

y = mx + b

y = -1/5x - 10
