Question

I need some clarification on this problem... please help! :)

What is the slope of the line x = -5?

Undefined

0

-5

5

Answer 1

hint: every point on this line has an x coordinate of -5

Answer 2

So do I have to write an equation?

Answer 3

what kind of line is this? horizontal? vertical? or diagonal?

Answer 4

It doesn't say, that's all that's there.. that's what I'm confused about..

Answer 5

look back at my hint

Answer 6

Is it C?

Answer 7

If you plug in any 2 points on this line into a slope formula, what do you get? take a shot...

Answer 8

Would (-5-1) and (0-(-5) be a good one?

Answer 9

what are two points that lie on this line?

Answer 10

I honestly don't know ): Do I just use any coordinate plane? Sorry for all the questions by the way, I'm new to this...

Answer 11

That's ok, remember every point on this line has an x coordinate of -5

Answer 12

so two points could be (-5,1) and (-5,2)

or (-5,10) & (-5, 15)

Answer 13

it doesn't matter what the y coordinate is
just make sure the x coordinate is -5

Answer 14

this is all because the equation is x = -5

Answer 15

once you have your two points, find the slope

Answer 16

Oh, okay, now I'm starting to understand! I'll figure out what the slope is...

Answer 17

use: m = (y2 - y1)/(x2 - x1)

Answer 18

I used yours and got -5 over 10, is that correct?

Answer 19

incorrect

Answer 20

keep in mind subtracting a negative is the same as adding

-5-(-5) = -5+5 = ???

Answer 21

Is that correct? ^^

Answer 22

no it's not

Answer 23

you should get 0 in the denominator, try again

Answer 24

and because you get 0 in the denominator, dividing by zero means the slope is undefined

Answer 25

Thanks!!!!!!!!!!
