Question

A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y = −10x + 3000. a) Graph the equation. b) Interpret the x-intercept and the slope.

Answer 1

The graph of the equation is:

The x intercept of 300 means the skydiver lands on the ground after 300 seconds. The slope of -10 means that the skydiver falls to the ground at a rate of 10 feets per second.
