we are given x here, so we already know that our first coordinate is equal to -2.
in order to find the next coordinate, we have to substitute x for -2 in the y=mx+b equation.
the equation is

so in substituting x for -2 we get

all we need to do is multiply â…” by -2, which gives us -1,3333.
we now have

so we add them together and get :

hope this helps!!<3
