Show your work. Is (1, -7) a solution to the equation y = x - 8? Choose the correct answer.

Question

a) yes
b) no

Answer 1

To determine if (1, -7) is a solution to the equation y = x - 8, we substitute x = 1 and y = -7 into the equation and see if both sides are equal.

Substituting x = 1 and y = -7 into y = x - 8:

-7 = 1 - 8

Simplifying the right side:

-7 = -7

Since both sides are equal, (1, -7) is indeed a solution to the equation y = x - 8.

Therefore, the correct answer is:

a) yes
