Question

Select the correct properties of slope below.
Multiple Response.

A.The slope of a line is always positive
B.The slope of a line which moves up from left to right is positive.
C.Some lines have no slope .
D.A steep line has a negative slope.
E.If two lines have the same slope then they are the same line.

Answer 1

A is false
B is true
C is true
D is false
E is false

Answer 2

A) false slope of course is not always positive so the first one fails
B) true going up from left to right is positive.
C) true/false some lines have no slope, this could be a trick question.
example x=3 is a lines going up and down, but is not a function and this has slope undefined
if we do not consider this a line, then all lines have a slope.
D) false steepness has nothing to do with the sign of the slope
E) false y=x+1 and y=x have same slope

Answer 3

Not sure about C

Answer 4

Hmmmmnm *-_-

Answer 5

both answers could work, there are many things it depends on.
1) does you teacher consider vertical lines to be lines
2) does you teacher consider infinity to be a real extended number or not
....

Answer 6

Its just a practice question

Answer 7

I know, just understand why I have a problem with the question and you are good:)

Answer 8

well I didn't know, but ....

Answer 9

I interpret "no slope" as m=0.

example: y=(0)x+3

Answer 10

hmm I don't.

Answer 11

0 slope is still a slope...

Answer 12

yes its 1

Answer 13

this is a very bad worded question

Answer 14

yea...

Answer 15

Tricky

Answer 16

What about the line x = 1?

slope = undefined

Answer 17

that what Im talking about

Answer 18

read up:)

Answer 19

slope 0 is still a slope, this is not a problem

Answer 20

its the x = that is a problem

Answer 21

imo

Answer 22

@flazingblazes @
> I interpret "no slope" as m=0.

That is not the case.

A vertical line has no slope.
A horizontal line has a slope of 0.

Because of that, my thinking on this --> C. Some lines have no slope . TRUE

Answer 23

Nice I get you

Answer 24

Thanks!

Answer 25

the real answer is of course true, now what your teacher means .....
if she is talking about functions then x=1 is not a function and does not count

Answer 26

Either way talk to your teacher about it, and he/she will be impressed:)

Answer 27

Thanks
