Question

Is (2, -7) a solution to the equation y = x +9 yes no

Answer 1

No

Explanation:

Answer 2

We have the following:

`y=x+9`

we replace the value of x which is 2, if it is a solution the result must be -7, otherwise it is not a solution of the equation

`y=2+9=11`

which means that the point (2, -7) is not a solution of the equation
