## Algebra and Trigonometry 10th Edition

To find the slope between two points, we use the slope formula. The slope formula is the change in the y values over the change in the x values. Slope = $\frac{y_{final} - y_{initial}}{x_{final} - x_{initial}}$ The final and initial points do not matter. In this example, the initial point will be (5,-2) and the final point will be (-1,4). However, either point can be considered the final point and either point can be considered to be the initial point without changing the slope. Using the slope formula: Slope = $\frac{4 - (-2)}{-1 - 5}$ = $\frac{6}{-6}$ = -1
