Answer:

Step-by-step explanation:
We are going to use the identity
because this identities right hand side matches your expression where
and
.
So we have that
is equal to
.
The answer is y=(1/2)x -5
You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m
Then work out like a one step equation
8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
