The x-intercept is the point where the graph crosses the y-axis (horizontal axis) and the y-intercept is the point where the graph crosses the x-axis (vertical axis).

Question 13

A hiker is hiking down a canyon toward the canyon floor. On the graph below you can see her height above the canyon floor as a function of time.

What is the best interpretation of the x-intercept?

Accepted Answer

The x-intercept, (18, 0), shows that in 18 minutes, the height of the hiker above the canyon floor will be zero; in other words, the hiker will reach the canyon floor in 18 minutes.

Answer

The x-intercept, (0, 18), shows that in 18 minutes, the height of the hiker above the canyon floor will be zero; in other words, the hiker will reach the canyon floor in 18 minutes.

Answer

The x-intercept, (0, 360), shows that in 360 minutes, the height of the hiker above the canyon floor will be zero; in other words, the hiker will reach the canyon floor in 360 minutes.

Answer

The x-intercept, (0, 360), shows that in 360 minutes, the height of the hiker above the canyon floor will be zero; in other words, the hiker will reach the canyon floor in 360 minutes.

Question 14

A hiker is hiking down a canyon toward the canyon floor. On the graph below you can see her height above the canyon floor as a function of time.

What is the best interpretation of the y-intercept?

Accepted Answer

The y-intercept, (0, 360), shows that at time = 0 minutes, the hiker is 360 feet above the canyon floor.

Answer

The y-intercept, (0, 360), shows that in 360 minutes, the height of the hiker above the canyon floor will be zero; in other words, the hiker will reach the canyon floor in 360 minutes.

Answer

The y-intercept, (360, 0), shows that at time = 0 minutes, the hiker is 360 feet above the canyon floor.

Answer

The x-intercept, (0, 360), shows that in 360 minutes, the height of the hiker above the canyon floor will be zero; in other words, the hiker will reach the canyon floor in 360 minutes.

Question 19

Maria has a cell phone plan that uses the equation y = 0.55x + 14, where y represents the base plan cost and x represents the number of minutes used, to determine the amount of her cell phone bill each month, before taxes and fees. What is the base cost of the plan (y-intercept) before minutes are used?

Accepted Answer

The y-intercept, (0, 14), shows that if Maria does not use her cell phone at all during a month to make calls, she will pay a $14 fixed charge.

Answer

The y-intercept, (14, 0), shows that if Maria does not use her cell phone at all during a month to make calls, she will pay a $14 fixed charge.

Answer

The y-intercept, (0, 14), shows that if Maria uses her cell phone for 14 months to make calls, she will pay a $0 fixed charge.

Answer

The x-intercept, (14, 0), shows that if Maria does not use her cell phone at all during a month to make calls, she will pay a $14 fixed charge.

Question 20

Maria has a cell phone plan that uses the equation

y = 0.55x + 14, where y represents the base plan cost and x represents the number of minutes used, to determine the amount of her cell phone bill each month, before taxes and fees. How many minutes used does the base cost represent (x-intercept), before additional minutes are used?

Accepted Answer

The x-intercept, (-25.45, 0), shows that the fixed monthly charge is approximately equal to the amount of money that 25.45 minutes cost.

Answer

The x-intercept, (0, -25.45), shows that the fixed monthly charge is approximately equal to the amount of money that 25.45 minutes cost.

Answer

The x-intercept, (14, 0), shows that if Maria does not use her cell phone at all during a month to make calls, she will pay a $14 fixed charge.
