Question

Arrange the slopes from flattest to steepest.

-3/2, 0, 4/3, undefined

Answer 1

To arrange the slopes we need to take their absolute values.
1. Undefined slope means a vertical line, so it is going to be steepest.
2.|4/3| = 4/3
3.|-3/2| = 3/2
4. 0 means horizontal line.

From flattest to steepest: 0, -3/2, 4/3, undefined.
