Question

A line is parallel to the y-axis on a coordinate plane. Which best describes the slope of the line

Answer 1

Answer:

well if it is parallel it would but 2 lines going in the same direction. it will never touch

Step-by-step explanation:

Answer 2

Answer:

The slope of this line is undefined.

Explanation:

The slope of a line is rise over run, where the rise is the change in y value and the run is the change in x. Since there is no change in x when a line is parallel to the y-axis, any slope would mean you would divide by 0.

$m=\frac{rise}{run}\\m = \frac{rise}{0} \\m= \frac{anything}{0}$

Since you cannot divide by 0 the answer will always be undefined no matter what the numerator is. The slope of any vertical line will be undefined.
