Question

How can we find out whether or not a point is on the line?

Answer 1

To determine if a point is on a line you can subsitute the x and y coordinates into the equation.. If the values equal one another, then the point must be on a line.

Explanation:

For example if the x - 3y = 11 and the point is (2, -3) plug in

2 - 3(-3) = 11

2 + 9 = 11

11 = 11

Answer 2

Plug the points into an equation

Explanation:

To find out if a point is on a line, you can plug the points back into an equation. If the values equal one another, then the point must be on a line.
