I am not sure where to start on this equation. I know that m = y2-y1 over x2-x1, but I am not sure how to set this one up. Any suggestions or clues?

Thank you!

You must have heard the alternate way to define slope as rise/run

the rise is 1800 ft, for a run of 3.25 miles.

slope usually has not units (they cancelled out in the calculation), so you must have the same units.

there are 5280 feet in 1 mile, so change the 3.25 miles into feet

then form the fraction,

I had it reduce to 15/143

if you want to set it up your way, you would have two points (0,0) and (17160,1800) now do the y2... bit stuff
