Answer 2

You know the idea..

What did you pick?

Answer 3

line m with the slope 3/4 is parallel

Answer 4

Its slope should be -3/4 to be parallel to the original line. right?

Answer 5

Yes, right. So does it mean that it is perpendicular.

Answer 6

I think it is neither!

Answer 7

Okay! Let's move on to the next one. I was thinking perpendicular.

Answer 8

\[\Huge\color{red}\checkmark\]
why?

because their product of slopes is -1

agree?

Answer 9

Yes! I agree!

Answer 10

Excellent!
Next?

Answer 11

line n with slope 4/3 is perpendicular

Answer 12

Yes, correct.
Because their product of slopes is -1.


next..

Answer 13

and line p with slope -4/3 is parallel

Answer 14

Why?
Does it have the same slope of the reference line?

Answer 15

Yes, I think so.

Answer 16

Is \(-\frac{4}{3}\) equal to \(-\frac{3}{4}\)?

Answer 17

No

Answer 18

So it is not parallel!
Is it perpendicular?

Answer 19

Yes! :)

Answer 20

why?
Is their product equal to -1?

Answer 21

I'm sorry, no it's not equal. It's neither.

Answer 22

Answer 23

And the last one is parallel

Answer 24

Sure?

Answer 25

I think I'm sure.
