5.1) We need to find the slope.
. Plug the y-coordinates and the x-coordinates into the formula.
That would be either
or
. Hint: The answer is a negative integer.
5.2) Set up the equation,
. Plug in the answer from 5.1 for
. Then choose
either point. If you choose (4, -2), then plug in 4 for
and -2 for
. Otherwise choose (3,8); plug in 3 for
and 8 for
. Either point will yield the same result, next step.
5.3) Solve equation 5.2 for
.
5.4) Set up the equation
again. Plug in the answer from 5.1 for
. Plug in the answer from 5.3 from 5.1 for
. Leave the
