#### Explanation:

To check whether a point lies on the line, substitute either

Let's substitute

This corresponds to the y-coordinate in (1, -1). Thus the point (1, -1) lies on the given line.

Substitute

For (-3, 0) to lie on the line, putting

Similarly, (5,4) does not lie on the line. Try plugging in one of the values to see it.

graph{y = 2x -3 [-10, 10, -5, 5]}
