Question

Write a formula for the slope of a line that is perpendicular to the line through the points (x1, y1) and (x2, y2)

Answer 1

it is the "negative reciprocal"
compute the slope, the flip it and put a minus sign in front

Answer 2

by "compute" i really just mean "write it"

Answer 3

Thank you, so the answer would be m = -x2-x1/y2-y1?

Answer 4

yes. of the minus sign is in front of the whole thing

Answer 5

\[-\frac{x_2-x_1}{y_2-y_1}\]

Answer 6

Awesome, how do I give you a medal?

Answer 7

you can click on "best response" but honestly i have plenty
bought my bike with the first 1000

Answer 8
