The line graphed below has a slope of

-3
-1/3
1/3
3

The line drops 3 squares for each one it moves to the right, so the slope is
.. -3/1 = -3

The 1st selection is appropriate.


Given the choices, you can tell at a glance that -3 is the correct one. When it goes down to the right, the slope is negative. when the angle is steep, the slope has a magnitude greater than 1. Of the negative choices offered, {-3, -1/3}, the obvious choice is -3.

A line has a slope of ±1 when it makes a 45° angle with the x- and y-axes. Steeper than that is a slope whose magnitude is greater than 1. Shallower than that, and the slope has a magnitude less than 1.

The answer you are looking for is right in front of you it’s c. 3/20
