Question

Does (2,5) make the equation y = 7x2 true? yes no

Answer 1

If we need to determine if the point (2,5) satisfies the equation y=7x^2.

We must substitute (x,y):

`\begin{gathered} y=7(2)^2 \\ y=7\cdot4=28 \end{gathered}`

Then, the point is not a solution of the equation so it is not true.
