The graph shows the altitude, a, of a plane, in feet, after t minutes. What is the rate of ascent of the airplane?
1 answer:
The rate of ascent is also known as the slope. To find the slope, we will follow the steps below.
Step 1) Choose two points on the line
Point 1: (4, 500)
Point 2: (8, 1000)
Step 2) Use the slope formula to find the slope
m = (y2 - y1) / (x2 - x1)
m = (1000 - 500) / (8 - 4)
m = 500 / 4
m = 125 feet per minute
