Question

two lines are perpendicular. if one line has a slope of 1/21 what is the slope of the other line

Answer 1

if line `A` and `B` are perpendicular to each other, and line `A` has a slope of `m`, then line `B` would have a slope of `-1/m`

Answer 2

so its -1/21

Answer 3

not exactly

Answer 4

in your case m=1/21
so -1/m = -1/(1/21)

Answer 5

thx

Answer 6

that is not it.

Answer 7

you have to simplify that

Answer 8

ok
yea its 1/21

Answer 9

or -21
