The equation for finding the slope of a line is

. After substituting in the points, we get
we know that
The unit rate is $0.65 per foot
so
To find out the cost, multiply the unit rate by the length of the rope
so
0.65*(10.8)=$7.02
therefore
<h2>The cost is $7.02</h2>
The answer to that would be 30
