The first problem is a F OI L problem. First write it like this:

The second question, any time you need the y intercept, just let x = 0 and solve for y.

2x - 3y = 6
2(0) - 3y = 6
-3y = 6

Divide both sides by -3:

Sometimes this is written in (x,y) form (0,-2). Remember in this form, it's always in alphabetical order, with the x first, and the y second.

Good luck on your test!! Then again, it's NOT luck--it's PREPARATION!!!
