For the first two, solve the equations for y. Set up a table of arbitrary x values and see what the corresponfing y value is.

For the 3rd one, solve for x to get x = 3.Code:y = x - 2 y = 3x - 6 x | y x | y ----- -------- 0 |-2 0 |-6 1 | 1 | 2 | 2 | -1| -1 | -2| -2 |

You may or may not know that this is the graph of a vertical line through x=3.

Are you sure you copied the last one correctly.
