Question

help?!?!

Answer 1

you need to plot these points with graph paper and see

Answer 2

ok

Answer 3

I was thinkin b?

Answer 4

sorry my answer was not helpful, i saw it as i plotted the points

Answer 5

no that is not it
you need to compute the slope of AB and of AC do you know how to do that?

Answer 6

idk ..

Answer 7

A is \((-2,4)\) and B is \((6,0)\) slope is
\[\frac{y_2-y_1}{x_2-x_1}\] in whatever order you choose
you get
\[\frac{0-4}{6-(-2)}=\frac{4}{-8}=-\frac{1}{2}\]

Answer 8

actually it was
\[\frac{-4}{8}=-\frac{1}{2}\]

Answer 9

slope of AC
A is \((-2,4)\) and C is \((-4,0)\) slope is
\[\frac{4-0}{-2-(-4)}=\frac{4}{2}=2\]

Answer 10

since \(-\frac{1}{2}\) is the negative reciprocal of \(2\) you know AB and AC are perpendicular

Answer 11

so...a?

Answer 12

I mean c

Answer 13

no AB is perpendicular to AC

Answer 14

yes C
it is always C
