Quizplus · Accepted Answer

A line with an undefined slope is a vertical line, meaning all points on the line share the same x-coordinate. The points $( 1,3 )$ and $( 1,1 )$ both have an x-coordinate of 1, just like the given point (1,2).

The Point (1,2) Is on a Line with Undefined Slope (0,2)( 0,2 )(0,2)

The Point (1,2) Is on a Line with Undefined Slope $( 0,2 )$
