Question

Line N passes through the points (-1,4) and (-1,-4)Which is true of line N?

Answer 1

Line N is a vertical line with an undefined slope

Explanation:

To find slope we do (y2-y1)/(x2-x1)

So we do that with (-1,4) and (-1,-4)

(-4-4)/(-1-(-1))

-8/0

Since the denominator is 0, that means the slope is undefined because you cannot divide by 0
