Question

12) an airplane covered 22 miles of its route while decreasing its altitude by 33,000 feet. find the slope of the airplane's line of descent. Round to the nearest hundreth. {Hint: 1mi= 5280 feet}

Answer 1

slope = y/x

The x component is 22 miles
The y component is -33,000 ft or -6.25 miles, negative since the airplane is descending.

slope = y/x = 22 miles / -6.25 miles
slope = -3.52
