We are given two points: (-1, -1) and (1, -4). Slope is calculated as the change in y over the change in x, or rise over run.
The change in y is the difference of the two y coordinates (it doesn't matter the order): -1 - (-4) = 3
The change in x is the difference of the two x coordinates (this order depends on the order that you subtracted the y coordinates; they must be the same order): -1 - 1 = -2.
So, the slope is 3/-2
It’s D, when lines are perpendicular, the slopes of the lines are opposite reciprocals.

tbh i just used another app to help me help you i hope this is right the app i used is always spot on with answers :)
