Finding Rate of Change and Constant of Proportionality from Tables

What are the two main concepts discussed in the video?

• Multiplication and division

• Geometry and algebra

• Rate of change and proportionality

• Addition and subtraction

What is the rate of change?

• The product of x and y

• The ratio of the change in x over the change in y

• The difference between x and y

• The sum of x and y

Which symbol is used to represent change in mathematics?

• Gamma (γ)

• Beta (β)

• Alpha (α)

• Delta (Δ)

What is the formula for slope?

• x1 * x2 over y1 * y2

• y1 + y2 over x1 + x2

• x2 - x1 over y2 - y1

• y2 - y1 over x2 - x1

What does a constant rate of change indicate about a relationship?

• It is linear

• It is non-linear

• It is exponential

• It is quadratic

What are the criteria for a function to be proportional?

• It must be non-linear and have a negative slope

• It must be linear and pass through the origin

• It must be non-linear and pass through the origin

• It must be linear and have a positive slope

What is the constant of proportionality represented by?

• P

• M

• K

• N

What does a negative slope indicate about the relationship between x and y?

• As x decreases, y increases

• As x decreases, y decreases

• As x increases, y increases

• As x increases, y decreases

What does it mean if the constant of proportionality values are not the same?

• The relationship is linear

• The relationship is proportional

• The relationship is not proportional

• The relationship is quadratic

What is the first step in the carrot method?

• Subtracting the values

• Calculating the sum of values

• Multiplying the values

• Drawing arrows (carrots) to show changes
