Question

Is the point (-2,5) a solution for the equation y = 10 + 4x. Explain why and ensure that math

evidence is in your response.

Answer 1

No, the point (-2, 5) is not a solution.

Explanation:

To see if the point is a solution, plug the given values for x and y into the equation:

y = 10 + 4x

5 = 10 + 4(-2)

5 = 10 - 8

5
`\\eq` 2

Because the two sides aren't equal to each, the point (-2, 5) can't be a solution.
