CPM Homework Help : ACC7 Problem 5-47

Ariyonne claims that $(3,6)$ is the point of intersection of the lines $y=4x−2$ and $y=\frac{1}{2}x+5$ . Is she correct? How do you know?

Hint:

A point of intersection means that a certain point makes both equations true.

More Help:

Substitute Ariyonne's point into both equations. Does it make them both true?
