Answer:


y=(20)/(7)x+20

Explanation:

Use the point slope form of the equation of a straight line:


y-y_1=m(x-x_1)

where m is the slope and
(x_1, y_1) is a point on the line

Substituting m = 20/7 and point (-7, 0) into the formula:


\implies y-0=(20)/(7)(x+7)


\implies y=(20)/(7)x+20

The y-intercept is (0, 20)
