# Chapter 8 - Coordinate Geometry and Linear Systems - 8.3 - Slope of a Line - Problem Set 8.3: 54

#### Answer

The easiest way to find two coordinates on a line is to first plug in 0 for x and solve for y and then to plug in 0 for y and solve for x. Once this is done, these two points can be plugged into the equation $m =\frac{y_2-y_1}{x_2-x_1}$, where m is the slope.
