Question

I forgot how to do this so please help me.

Answer 1

Draw a straight line that goes through the point (0,4) and (20,0)

Explanation:

The y-intercept is equal to 4, since the function is already in y=mx+b form, where b is the y-intercept.

To find the x-intercept, we substitute 0 into y or in this case the f(x).

0 = -1/5 (x) + 4

1/5 x = 4

x = 20

The x-intercept is 20.
