undefinded slope means a vertical line...meaning 'y' = 0 so which is it?

tyteen4a03 · Answer

The equation of a slope is $\frac{y2-y1}{x2-x1}$. Anything that makes x2 - x1 zero will make the slope undefined, since you cannot divide by zero.

is it C :o

anonymous · Answer

undefined slope means both the first coordinates are the same

we all know it's that one letter with the points  :P
$$\frac{ 5-0 }{ -2+2 }=\frac{ 5 }{ 0 }$$
