Question

How do i find a slope for y=5?

Answer 1

slope is change in y / change in x, so you have a change in y = 0, so 0 / change in x (anything other than 0) give you ?

Answer 2

0

Answer 3

m=0

Answer 4

yep

Answer 5

it is a horizontal line, so there is no change in y

Answer 6

Thanks can I ask you for help on another one?

Answer 7

and the slop for x = 3 is ? ....
in this case you have the change in x = 0 and the change in y = infinity, so infinity / 0 is ? ...

Answer 8

0

Answer 9

No actually, dividing by 0 is undefined, so the slope for x = 3 is undefined

Answer 10

so why is y=5 not undefined
