Question

What is the slope of the line containing
points (2, -8) and (-10,-4)

Answer 1

-1/3

Explanation:

The slope can be calculated 2 ways. First, you can use the slope formula,
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`. 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.
