Question

What is the equation of the line that passes through the point (7,-3) and has an undefined slope?

Answer 1

X = 7

Explanation:

Any line with a undefined slope is a vertical line, which goes up and down.

Since this is a vertical line, and our x-value is 7, this means that the vertical line has the x-coordinate 7 at all times, making the equation x = 7.
