# Chapter 8 - Coordinate Geometry and Linear Systems - 8.4 - Writing Equations of Lines - Problem Set 8.4: 45

#### Answer

In order to solve this problem, we first find the slope, for the two points can be plugged into the equation $m =\frac{y_2-y_1}{x_2-x_1}$, where m is the slope. We then create a proportion and cross multiply. Finally, we use addition and subtraction to put the equation into the desired form.
