The trail starts at p(−2, 2) and goes to q(5, 2). it goes from q to r(5, −5) and then to s(8, −5). what is the total length (in units) of the biking trail?

If you draw this out on a graph you can count the units but if not you must take the change from P(-2) to Q (5) Ignore the y's since they're the same. So there is a space of 7 between the numbers which can found found by counting up from -2. Q(2) to R(-5) ignore the x's since they're the same. So on and so forth ending up with an answer of 17units traveled
