Slope = (4 − 7)/(40 − 20) = −3/20 = −0.15 km/min.
Equation: y = 10 − 0.15x.

At x = 0, y = 10, so Manuel started 10 kilometers from the finish.
Set y = 0: 0 = 10 − 0.15x ⇒ x = 10/0.15 = 66 2/3 minutes = 66 minutes 40 seconds.

Answer: started 10 kilometers away; he ran 66 2/3 minutes (66 min 40 sec).
