This problem is a checkpoint for solving for one variable in an equation with two or more variables. It will be referred to as Checkpoint 4B. Homework Help ✎

Rewrite the following equations so that you could enter them into a graphing calculator. In other words, solve for $y$.

1. $x − 3(y + 2) = 6$

1. $\frac { 6 x - 1 } { y } - 3 = 2$

1. $\sqrt { y - 4 } = x + 1$

1. $\sqrt { y + 4 } = x + 2$
