Question

The slopes of three lines are given below.

m = -1/2
m = 3
m = 0

a. Determine the slope of a line that is parallel to a line with each given slope.

b. Determine the slope of a line that is perpendicular to a line with each given slope.

Answer 1

@Littlebird @DanJS @praetorian.10

Answer 2

A parallel line has the same slope as the other line that it is parallel to

Answer 3

The slope of a perpendicular line will have a slope that is the negative reciprical of the given lines slope...

IE ---> slope = 5
Perpendicular slope = -1/5 change the sign and flip the fraction over

Answer 4

So for m = -1/2

Parallel: m = -1/2
Perp: m = 2

Answer 5

Important note: A line perpendicular with the slope of 0 is undefined.

Answer 6

I need to reword that

Answer 7

No I get it!

Answer 8

I remember my teacher going over undefined slopes

Answer 9

yeah you hve the first right

Answer 10

m = 3

Parallel: 3
Perp: -1/3

Answer 11

yep

Answer 12

Do I have to write an actual like, like y = -1/3 + 2 or do I just write the slopes

Answer 13

It says determine the slope of a line for them, so I'm thinking just the slope

Answer 14

It is just asking for the slopes, you would need a point on the line to write its equation.

Answer 15

Thanks for the clarification @DanJS

As for the last one of m = 0

Parallel: 0
Perp: Undefined

Answer 16

right, zero slope is horizontal line, if you have a line perpendicular to that , it is a vertical line. the slope of a vertical line is infinity, or undefined

Answer 17

Couldn't have found the perp for that one without your advice @Littlebird

Answer 18

welcome

Answer 19

Thanks both of you @Littlebird @DanJS
