Question

please help me  c: ! Any line with an undefined slope is parallel to the......... x-axis, y-axis, or x=y ?

e.mccormick · Answer

Slope is change in y over change in x.  Undefined is a way of saying divide by 0.  So undefined slope is change in y over 0!  So, which do you think that would be?

anonymous · Answer

x=y ?

e.mccormick · Answer

$$\frac{y_1-y_2}{0}$$Means that $x_1-x_2=0$

e.mccormick · Answer

Not x=y, but what would cause the bottom numbers to cancel each other?

anonymous · Answer

y-axis right ?

e.mccormick · Answer

Yah.  Cause $x_1-x_2=0$ means the xs are all the same!

e.mccormick · Answer

The parllel to x-axis is when all the ys are the same, or 0 slope.  So that is how you can keep track of these.  No change in y and it is parallel to x, but no change in x and it is parallel to y.
