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 t = 0 to be 4500 ft. the linear graph shows the skydiver’s altitude at various times during her descent.

(a) identify the y-intercept. how does the y-intercept relate to the skydiver’s position relative to the ground? 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 x-intercept. what does the x-intercept mean in this context? explain.

(d) write an equation for the line.
