Question 5

Why is the rate of change negative in the example given?

Accepted Answer

Because the distance is decreasing

Answer

Because the distance is constant

Answer

Because the distance is increasing

Answer

Because time is moving backwards

Question 6

What does a negative rate of change indicate?

Accepted Answer

The Y values are decreasing

Answer

No change in values

Answer

The X values are decreasing

Answer

The Y values are increasing

Question 7

What does 'Y per X' represent in the context of the video?

Accepted Answer

Change in Y values over change in X values

Answer

Change in time over change in distance

Answer

Distance per hour

Answer

Speed of an object

Question 8

Can the concept of rate of change apply to scenarios without a story?

Accepted Answer

Yes, using any X and Y values

Answer

Yes, but only with distance and time

Answer

No, it requires a physical context

Answer

No, it only applies to stories

Question 9

How does the video suggest handling data tables without a clear story?

Accepted Answer

Use the same method as with a story

Answer

Ignore the table

Answer

Only focus on X values

Answer

Create a fictional story

Question 10

Why is understanding rate of change important?

Accepted Answer

To understand relationships between variables

Answer

To calculate the area of a shape

Answer

To solve for X only

Answer

To memorize data tables

Question 11

How do you calculate the rate of change with X and Y values?

Accepted Answer

Divide the change in Y by the change in X

Answer

Divide the total X by total Y

Answer

Multiply the change in X by the change in Y

Answer

Add the change in X to the change in Y

Question 12

What is the rate of change if you gain 12 Y's for every 3 X's?

Accepted Answer

4 Y's per X

Answer

3 Y's per X

Answer

15 Y's per X

Answer

12 Y's per X

Question 13

What does a rate of change of 4 Y's per X indicate?

Accepted Answer

For every X, Y increases by 4

Answer

For every 4 Y's, X increases by 1

Answer

For every X, Y decreases by 4

Answer

For every 4 X's, Y increases by 1

Question 14

If a data table shows decreasing Y values over increasing X values, what can be inferred?

Accepted Answer

Answer

The object is accelerating

Answer

The object is moving in reverse

Answer

The object is stationary
