For what value of y does the point (-3,y) lie on the line y = -3x + 4?

The point (-3,y) means that we have an x value that equals -3 and an unknown y value. So to find the unknown y value, plug in x=-3

plug in x=-3

Multiply

Add

So the y value equals 13. In other words, the point (-3,13) lies on the line

Here's a visual verification:
