Understanding Linear Relationships and Rates

The video tutorial introduces the concept of constant rate of change, starting with vocabulary such as linear relationships and constant rate of change. It explains how to find the constant rate of change using tables and the formula 'rise over run'. The tutorial provides examples and a practice problem for students to solve, emphasizing the importance of understanding changes in x and y values to determine if a constant rate of change exists.

What is a linear relationship?

• A relationship with a curved graph

• A relationship with a straight line graph

• A relationship with a zigzag graph

• A relationship with no graph

What does the constant rate of change represent in a linear relationship?

• The change in x values only

• The change in y values only

• The total sum of x and y values

• The rate of change between any two points

How do you find the constant rate of change using a table?

• By adding all x values

• By finding the differences between x and y values

• By subtracting y values from x values

• By multiplying x and y values

In the formula 'rise over run', what does 'rise' refer to?

• The difference between x and y

• The x-coordinate

• The y-coordinate

• The sum of x and y

What is the next step after identifying the differences in x and y values?

• Add the differences together

• Divide the differences to find the rate

• Multiply the differences

• Subtract the differences

What is the constant rate of change in the first example?

• 15

• 0

• 9

• 1

In the second example, what is the change in x values?

• 15

• 20

• 10

• 25

Why is there no constant rate of change in the second example?

• Because the changes in x and y are not proportional

• Because the y values are not consistent

• Because the table is incomplete

• Because the x values are not increasing

What should you do if the changes in x and y are not the same?

• Conclude there is no constant rate of change

• Ignore the differences

• Recalculate the values

• Assume a constant rate of change

What should students do with the practice problem?

• Ignore it

• Solve it and submit the answer

• Wait for the teacher to solve it

• Discuss it with peers
