Stages:

Slope (%) Approximate degrees Terminology 30 - 45 16.5 - 24 Very strong slope 45 - 70 24 - 35 Extreme slope 70 - 100 35 - 45 Steep slope > 100 > 45 Very steep slope
Also Know, what does a line with a slope of 0 look like? Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it. It will look like y = something.

Accordingly, what does it mean when a line is steeper?

In math, steeper means bigger so the slope of that line is bigger than the slope of the second skaters line. You may also notice that the skaters are going down the ramp from the left to the right. This makes the slope decreasing, or negative.

What kind of line has a slope of 0?

horizontal
