Constant Rate of Change Concepts

In this lesson, the teacher introduces the concept of the constant of proportionality, correcting the lesson number to five. The lesson covers verbal, algebraic, pictorial, and numeric representations of the constant rate of change, using a caterpillar's movement as an example. The teacher explains how to calculate the rate, represent it algebraically, visualize it pictorially, and use numeric tables. The lesson concludes with instructions on graphing the data.

What was the initial mistake made at the beginning of the lesson?

• The lesson number was incorrect.

• The topic was not introduced.

• The guest star was not mentioned.

• The video was paused.

How is the constant rate of change initially described in the verbal method?

• As a subtraction of time from distance.

• As a fraction of distance over time.

• As a multiplication of distance and time.

• As an addition of distance and time.

What is the first step in calculating the constant rate of change using division?

• Divide the distance by the time.

• Add the distance and time.

• Multiply the distance by the time.

• Subtract the time from the distance.

What is the decimal representation of the constant rate of change?

• 3.25

• 4.25

• 5.25

• 2.25

How is the constant rate of change represented algebraically?

• y = 3.25x

• y = 4.25x

• y = 2.25x

• y = 5.25x

What is the purpose of using a pictorial method?

• To visually understand the constant rate.

• To calculate the constant rate.

• Write an essay.

• Create a pie chart.

• Draw a map.

What is the first thing to do when setting up a graph?

• Set up your X and Y axes.

• Draw a circle.

• Write a paragraph.

• Create a list.
