Your answer would be y = 4x + 3.
Since we are already given the slope, we just need to find the y-intercept. We can do this by writing the equation as y = 4x + b, and then substituting in the coordinates that we are given. This gives us:
-5 = (4 × -2) + b
-5 = -8 + b
b = 3
So now we can write the whole equation as y = 4x + 3.
I hope this helps!
