Question

consider y=4x-7. is (-1,-3) a solution? explain how you know

Answer 1

Answer:

No, it is not a solution.

Step-by-step explanation:

If we substitute the values (-1,-3) in the equation, we get:

y=4x-7

(-3)=4(-1)-7

-3= -4 -7

-3 = -11

Now we know that these obviously aren't equal, so it is not a solution of this equation.
