Question

Is (-1, -10) a solution to this system of equations?

y = -8x + 7
y = 6x + 5
yes
no

Answer 1

No it is not if we’re to put them in I wouldn’t work

Answer 2

no

Explanation:

to check if (-1,-10) is a solution to the system of equations y = -8x + 7 and y = 6x + 5, we substitute x=-1 and y=-10 into both equations and check if both equations hold true.

y = -8x + 7 -10 = -8(-1) + 7 -10 = 8 + 7 -10 ≠ 15

y = 6x + 5 -10 = 6(-1) + 5 -10 = -1

Since (-1,-10) does not satisfy both equations simultaneously, it is not a solution to the system of equations.
