Respuesta :

Part b

we have

2y=-x-8

Remember that

the equation in slope intercept form is

y=mx+b

so

Isolate the variable y

divide by 2 both sides

2y/2=-(x/2)-8/2

y=-(1/2)x-4

Part c

we have

y-4=-3(x-3)

apply distributive property right side

y-4=-3x+9

Adds 4 both sides

y=-3x+9+4

y=-3x+13
