Question

Select the pair of equations whose graphs are perpendicular.

Answer 1

A.


2y = –3x + 5
2x + 3y = 4


B.


2x – 8y = 9
12x – 3y = 7


C.


y = 2x – 7
x + y = 3


D.


3x + 6y = 8
y = 2x – 8

Answer 2

@Mertsj

Answer 3

Solve each equation for y. Then multiply the slopes. If you get -1, they are perpendicular.

Answer 4

How do you do that?

Answer 5

You mean you don't know how to make the equation say y= ???

Answer 6

No multiply the slope

Answer 7

In this equation: y=2x-5
What is the slope?

Answer 8

2

Answer 9

In this equation: y=-1/2x + 6
What is the slope?

Answer 10

-1/2

Answer 11

multiply the slopes

Answer 12

-1?

Answer 13

Those lines are perpendicular.

Answer 14

What you just did was a an explanation you made yourself right?

Answer 15

Yes, Now you do the same with your answer choices. When you find one where you get -1 for the product of the slopes, you will know that is the answer.

Answer 16

Okay, I think it is A

Answer 17

yea its A

Answer 18

lol why did you copy @Mertsj image?

Answer 19

It is NOT A

Answer 23

ok thats nice im verry much aware of my own country and i could be but in MY OWN OPINION i think its A

Answer 24

And anyway, why don't you try that "personal opinion" stuff the next time you have a math test?

Answer 25

i do and ive never made below a 75 ! NEXT ?

Answer 26

Ugh I thought it was A!

Answer 27

and were you right ?

Answer 28

out standing at lest you had youer own opinion

Answer 29

@Mertsj says its wrong
