Question

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

Answer 1

I believe the y intercept is 4500 ft, since t=0, and the slope of the line would be 1500/( distance from t=0 to the x coordinate for 6000), the person is probably acending since it went from 4500 to 6000. Idk C D cause I don't have the graph
