find the slope of the line the slope formula is \[m = \frac{y_{2}-y_{1}}{x_{2}-x_{2}}\] so using your information you will have \[m = \frac{9 - 5}{3 - (-7)} \] when you evaluate the slope you will have the rate of change in the trail.

well when you simplify 4/10... there is a common factor of 2 in the numerator and denominator |dw:1366675171570:dw| hope this makes sense
