Question

The slope of line X between (-7, 6) and (-4, 4) is . What is the slope of line X between (-1, 2) and (5, -2)?

Answer 1

$$m = \frac{y_2 - y_1}{x_2 - x_1}$$

Answer 2

can i please get an answer trying to help my son and were not surre how to do it

Answer 3

Sure, but you have to understand how to do it as well.

Answer 4

Let's try to derive the equation for slope.
We know that, as time moves along, no values on the x-range are going to change. In other words, time is constant. The x-axis is straight; it has no curvature, see?
