Answer
Slope = 0.15
Work Step by Step
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 (4.8,3.1) and the final point will be (-5.2,1.6). 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 = $\frac{1.6 - 3.1}{-5.2 - 4.8}$ = $\frac{-1.5}{-10}$ = 0.15
