Question

The graph is titled Heights of Airplanes Over Time. The letter x is to the right of the horizontal axis which is labeled from 0 to 25 in steps of 2.5. The label time in minutes is below the graph. The letter y is above the vertical axis which is labeled from 0 to 6,000 in steps of 500. The label height in feet is to the left of the graph. A red solid line passes through the approximate points left parenthesis 0 comma 5,000 right parenthesis, left parenthesis 18 comma 2,200 right parenthesis, and left parenthesis 20 comma 2,000 right parenthesis. The line is labeled Airplane 1. A blue dashed line passes through the approximate points left parenthesis 0 comma 1,000 right parenthesis, left parenthesis 18 comma 2,200 right parenthesis, and left parenthesis 20 comma 2,300 right parenthesis. The line is labeled
Airplane 2.
The heights of two airplanes, Airplane 1 and Airplane 2, are modeled with the linear equations shown in the graph. X represents time in minutes, and y represents height in feet. Estimate the time when the airplanes are at the same height, and estimate their height at that time.
(1 point)
The airplanes are at the same height at approximately ___
The height of the airplanes at that time is approximately ___
2,200
2,800
17.5
20
8
1,900
18

Answer 1

The airplanes are at the same height at approximately 18 minutes.
The height of the airplanes at that time is approximately 2,200 feet.
