Algebra II EXPERT will help you survive & prosper

Use the formula for slope. But this time the unknown will not be m, because you put 6 there.

The unknown will be y

_{2 }(for which you substitute "y")._{ }All of the other quantities x

_{1}y_{1}and x_{2}will also be known constants.The job, then, is to solve for the unknown, "y".

Use your Algebra skills to ISOLATE y.
