Question

O is the center of the regular nonagon below. Find its perimeter. Round to the nearest tenth if necessary.

Answer 1

Explanation:

To find the slope of the line, we need to calculate the rise over the run between two points on the line. Let's choose the two points (0, -3) and (6, 3) as shown in the graph.

Rise = change in y = 3 - (-3) = 6

Run = change in x = 6 - 0 = 6

So the slope of the line is:

slope = rise/run = 6/6 = 1

Therefore, the slope of the line is 1.
