Answer:

y= -5x-13

Explanation:

start with the linear equation

y= mx+b

indentify what you already have.

x= -4 and y= 7 and m(slope)= -5

We are solving for b, so plug in what you have.

7= -5(-4)+b

Simplify.

7= 20+b

Subtract 20 on both sides.

-13= b

Rewrite your equation with the x and y values.

y= -5x-13
