I NEED HELP! Write an equation in slope intercept form of the line

y=-1x+2

Step-by-step explanation:

First plug all of them in

y=-1, slope=-1, x=3

so -1= -1(3)+b

Solve by multiplying

-1=-3+b

then solve for b,

so add 3 to both sides

-1+3=-3+3

x=2

Plug that into y=-1x+b

Answer is y=-1x+2
