To find slope use the equation. Y2-Y1/X2-X1

-45-32/7- (-4)=. -77/11 divide by 11

The slope is -7

Using the slope to find Y-Intercept:

You can use any points but since you’re given two use the easiest one to solve such as (-4,32)

Y=-7x
32=-7(-4)
32=28 subtract 28 from both sides
-28=4
Equation is y=-7x+4
