X+6=11
X-11=-6
5x=25
2x=10
2x+15=25
~45.25 because the formula for circumference is 2(3.14286)a or 2(3.14286)7.2

Slope is equal to the change in
y
y
over the change in
x
x
, or rise over run.
The change in
x
x
is equal to the difference in x-coordinates (also called run), and the change in
y
y
is equal to the difference in y-coordinates (also called rise).
Substitute in the values of
x
x
and
y
y
into the equation to find the slope.
