Question

Is (-1, -1) a solution to this system of equations?

y = -8x - 9
y = -5x – 6
yes
no

Answer 1

Yes

Explanation:

To see is (-1, -1) is a solution to the system, we can plug it into the system to check:

-1 = -8(-1)-9

-1 = 8-9

-1 = -1

-1 = -5(-1)-6

-1 = 5-6

-1 = -1

Both of the equations are true, therefore (-1, -1) is a solution to the system.
