Question

toni is testing her new model airplane. she starts its descent at an elevation of 1,200 feet. it descends at a constant rate of 200 feet per minute. you just found that the plane lands 6 minutes after it starts to descend. what point on the graph shows this? the plane lands 6 minutes after it starts to descend. we can see this at the point (\square, \square)

Explanation:

Step1: Identify independent variable

The independent variable is time (minutes since descent started), which is the $t$-axis (horizontal axis). When the plane lands, this value is 6 minutes.

Step2: Identify dependent variable

The dependent variable is elevation (feet), which is the $R$-axis (vertical axis). When the plane lands, its elevation is 0 feet.

Step3: Form the coordinate point

Graph points are written as (independent variable value, dependent variable value).

Answer:

$(6, 0)$
