Answer 1

@mathstudent55 and @phi

Answer 2

can you pick out two points on the line x= -5 ?

Answer 3

No thats all the information they gave me so i was thinking that it would be undefined because they didn't give me any points to start with

Answer 4

You should be able to find two points on the line x=-5

for example: (-5,1) and (-5,2) are on the line (x is -5, and y can be anything)

to find the slope, find change in y divided by change in x
m= (2-1)/(-5 - (-5)) = 1/0

divide by 0 is not allowed because you get an undefined result.

so the slope is ?

Answer 5

undefined

Answer 6

or you can just remember, x=-5 is a vertical line, and vertical lines have undefined slope.

Answer 7

okay thank you

Answer 8

can you help me with another one

2

-2

-1

Answer 9

@phi

Answer 10

can you find the change in y divided by the change in x?

Answer 11

I think I figured it out

y2 - y1
-------
x2 - x1

-2 - 4 -6
------ -------- = -2
-1 - (-4) 3

Answer 12

yes
