Question

Plzhelp with this math

Answer 1

The answer is A,C, D. That is because we have to substitute the values -6 for x and -1 for y in the equations given. We substitute the values and see if the answer is true

Answer 2

Just to help you out in how to solve this just plug in every x of an equation -6, and in every y, -1. Plug these two number in every equation and see if it equal each other.Example:

y =4x +23

-1 = 4(-6) + 23

-1 = -24 + 23

-1 = -1

it shows that (-6,-1) is a solution to this equation

Letter A is one answer, let's see if you can find the others
