The equation is y= -1.4x +12 , and the y-intercept is 12

Step-by-step explanation:

Given that A (8,0) and B (3,7) you can find the slope

m=Δy/Δx

Δy=7-0=7

Δx=3-8=-5

m= -7/5

Given point D(5,5) the equation for slope will be;

m=Δy/Δx

- 7/5 =y-5/x-5

-1.4 =y-5/x-5

-1.4(x-5) = y-5

-1.4x+7=y-5

-1.4x+12=y

y= -1.4x +12 ⇒equation

12= y-intercept
