Start with the point-slope form: .
Then you substitue in the slope and coordinates from the point:
You don't do a lot of clean up to the form, with the exception of turning "minus negative 7" into "plus 7".

Answer:
80 mm
Step-by-step explanation:
Pythagorean theorm can be applied here to solve for the length of the last leg, +
=
, where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:
b = √c^2 - √a^2
= √(82)^2 - √(18)^2
= √6724 - √324
= √6400
= 80 mm
