y = 2x + 5

y = -2x

Answer 1

@iGreen

Answer 2

@shinalcantara

Answer 3

remember that parallel lines are having the same slope

Answer 4

what are the slopes of the two lines?

Answer 5

y = mx + b
m = ?

Answer 6

-2 and 2

Answer 7

since they are not having the same slope, then they are parallel or not?

Answer 8

nope

Answer 9

correct

Answer 10

thanks!

Answer 11

If Segment QR || Segment TU and the slope of Segment TU is 3, then the slope of Segment QR is ___.

Answer 12

what about this one?

Answer 13

It says Segment QR and Segment TU are PARALLEL, which means they have THE SAME SLOPE.

TU's slope is 3, so what's QR's slope going to be? @puppylover234

Answer 14

3? ok what about this one then. If Line AB has a slope of -1/2 and is perpendicular to Line CD, then the slope of line CD is ___.

Answer 15

Yep, you got it.

Answer 16

Perpendicular lines have OPPOSITE slope, so what's the opposite of -1/2?

Answer 17

2/1?

Answer 18

Yep! Or just 2.

Answer 19

so my answer would be 2?

Answer 20

Yes. 2/1 works too..it's the same thing as 2.

Answer 21

okay thanks! what about this kind ? What is the slope of the line perpendicular to segment EG if the coordinates of E and G are (-3, 2) and (2, 0)?

Answer 22

@iGreen can you help?

Answer 23

@chosenmatt can you help?

Answer 24

@puppylover234 Close this question and open another one..just ask one question per post.

Answer 25

ok i just did
