Question

Y=-8x - 5
y=-4x - 5
what is the solution ?

Answer 1

y=-8x-5
y= -4x-5
> -8x- 5 = -4x-5
x= 0 (plug this into -4x-5)
> y= -4 (0) -5
y= -5
the answer is (0, -5)

Answer 2

(0,-5) x= 0; y= -5

Explanation:

You can solve by using substitution. This means to solve for x on one of the equations then substituting x for the other equation and solving it.
