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.

Code:

y = x - 2                   y = 3x - 6

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