Answer
The greater the absolute value of the slope, the more quickly the line rises or falls.
Work Step by Step
Consider the lines:
$y=0.5x$
$y=x$
$y=2x$
$y=4x$.
We graph the lines. We notice that the greater the slope, the more quickly the line rises.
Consider the lines:
$y=-0.5x$
$y=-x$
$y=-2x$
$y=-4x$.
We graph the lines. We notice that the greater the absolute value of the slope, the more quickly the line falls.
Therefore, we conclude the greater the absolute value of the slope, the more quickly the line rises or falls.
