Answer:
y= -2x-7
Step-by-step explanation:
Start with the linear equation formula.
y= mx+b
identify what you already have.
x= -2 and y= -3 m(slope)= -2
we are trying to find b, so plug in what you have.
-3=-2(-2)+b
simplify.
-3= 4+b
subtract 4 on both sides.
-7= b
set up your equation without the x and y value.
y= -2x-7
