Answer:
-1/3
Step-by-step explanation:
The slope can be calculated 2 ways. First, you can use the slope formula, [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. Plugin the values and solve. This comes out to (-4+8)/(-10-2). When you compute this it equals 4/-12. Then, simplify to -1/3.
You can also count out the change in units. Since slope is rise over run; it is equal to the change in x over the change in y. The y-value increases by 4 while the x-value decreases by 12. Once you simplify you get the final answer of -1/3.
