2. A skydiver jumps from a plane from an altitude of 6000 ft. An observer on the ground measures the skydiver's
altitude at time to to be 3600 ft. The linear graph shows the skydiver's altitude at various times during her
descent

(a) Identify the x-intercept. What does the x-intercept mean in this context? Explain
(b) Determine the slope of the line. According to the slope, is the skydiver ascending or descending and
what is the rate of ascent or descent? Explain.
(c) identify the y-intercept. How does the y intercept relate to the skydiver's position relative to the
ground? Explain
(d) Write an equation for the line
