Question

What is the slope of the line that is perpendicular to y = 2x – 3?

How do I do this? Please don't give me the answer.

Answer 1

y=mx+b
For two lines to be perpendicular, their two slopes (m) must be -1 when it gets multiplied.
y=2x-3
2 represemts m in y=mx+b, so the slope is 2
2*(slope of other line)=-1

Answer 2

2

Answer 3

Y=(slope)x+y-intercept
thats why

Answer 4

Okay so, y = 3x – 3

the slope would be 1/3?

Answer 5

no its just 3

Answer 6

or 3/1

Answer 7

Slope of which line?
y=3x-3 or the line perpendicular to y=3x-3?

Btw dont listen to the person that posted after me.
It is not correct.

Answer 8

take the original slope

flip the fraction and flip the sign to get the perpendicular slope

Answer 9

so for example, if we had the original slope to be 2/7, then the perpendicular slope would be -7/2

another example
original: -4/9
perpendicular: 9/4

these are just examples and none of this is the answer

Answer 10

wait.
it wants the parallel to y = 3x - 3

Answer 11

parallel lines have equal slopes

Answer 12

How are you skipping to another equation and going from perpendicular to parallel?
Are you done with your first question?

Answer 13

okay so it'd be three

Answer 14

?

Answer 15

yup

Answer 16

the slope of the first one, the perpendicular thing, would be -2 since apparently it's the opposite of the original.

Answer 17

sloppycanada, you forgot to flip the fraction

Answer 18

think of 2 as 2/1

Answer 19

So it'd be -1/2? Since it's positive in the original?

Answer 20

yeah if +2/1 is the original slope, then -1/2 is the perpendicular slope

Answer 21

What is the slope of the line that is parallel to y = 3x – 3?

so for this it'd just be 3?

Answer 22

yep

Answer 23

Thanks a bunch!
