Answer:
[tex]y=\dfrac{20}{7}x+20[/tex]
Step-by-step explanation:
Use the point slope form of the equation of a straight line:
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and [tex](x_1, y_1)[/tex] is a point on the line
Substituting m = 20/7 and point (-7, 0) into the formula:
[tex]\implies y-0=\dfrac{20}{7}(x+7)[/tex]
[tex]\implies y=\dfrac{20}{7}x+20[/tex]
The y-intercept is (0, 20)
