Graph the system of equations on your graph paper to answer the question. {y=2x+7

y=-4x-5

What is the solution for the system of equations?

Y = 2x + 7

y = - 4x - 5

sub one y in for the other

2x + 7 = - 4x - 5

2x + 4x = - 5 - 7

6x = - 12

x = - 12/6

x = - 2

y = 2x + 7

y = 2 (-2) + 7

y = - 4 + 7

y = 3

solution is (-2,3) <==
