Question

Which equation would you use to find out if the two lines in the graph are parallel?

Answer 1

A: 4-1/-2 -1 = 3-1 / 3-1
B: 4-1/-2 -1= 3-(-1)/3-1

Answer 2

Do you know how to find slope?

Answer 3

C: 4-1/1-(-2) = 3-(-1)/3-(-1)
and no

Answer 4

Take the two ordered pairs that are given. subtract the y values. subtract the x values in the same order as you did the y values. Put the first answer over the second answer.

Answer 5

D: 1-(-2) / 4-1= 3-1/ 3-1

Answer 6

Yes I remember how to do slope now

Answer 7

Put the change in y on the top.

Answer 8

Okay

Answer 9

\[m=\frac{4-1}{1-(-2)}=\frac{3}{3}=1\]

Answer 10

okay well at the end isn't it = 3-(-1)/ 3-(-1)

Answer 11

How can you determine if the given lines are perpendicular

Answer 12

Lolwolf???

Answer 13

Two lines are perpendicular if, for some slope \(\frac{a}{b}\) the other has a slope of \(-\frac{b}{a}\).
