Question

what is the slope of y=5?

Answer 1

slope is 0

Answer 2

here's a hint:

horizontal lines = 0 slope
vertical lines = undefined slope

so what do you think is y = 5? horizontal or vertical?

Answer 3

Slope=0

Answer 4

slope is rise/run
rise is 0 and run is unknown
therefore slope is 0

Answer 5

HOY - Horizontal, 0 slope, Y= a number! :)

So in this case, slope would be zero.

Also useful to know is VUX: Vertical, Undefined slope, and X = a number.

Answer 6

HOY and VUX are mnemonics, if you learn them, it will make your life a lot easier :D
