Question

the graph shows a plane. the line is slanting and therefore has a slope. it takes the plane minutes to touch the ground.

Explanation:

Step1: Analyze the graph context

The graph shows the elevation of a plane over time. As time increases, elevation decreases, which means the plane is descending.

Step2: Determine slope nature

The line is going down - ward from left to right. In a coordinate - plane, a line that goes down - ward from left to right has a negative slope.

Step3: Find landing time

The plane touches the ground when the elevation is 0 km. Looking at the x - axis (time), when the elevation (y - axis) is 0, the time is 15 minutes.

Answer:

The graph shows a plane descending. The line is slanting downward and therefore has a negative slope. It takes the plane 15 minutes to touch the ground.
