Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

Front

How do you calculate the unit rate from a given distance and time?

Back

To calculate the unit rate, divide the total distance by the total time. For example, if a person travels 300 feet in 2.5 minutes, the unit rate is 300 feet / 2.5 minutes = 120 feet per minute.

Front

What is the value of x in the equation 2x + 10 = 70?

Back

The value of x is 30.

Front

What does the equation y = 20x represent in terms of unit rate?

Back

The equation y = 20x represents that for every minute (x), Susan travels 20 floors (y), making the unit rate 20 floors per minute.

Front

Is the table proportional if the ratios of the quantities are not constant?

Back

No, a table is not proportional if the ratios of the quantities do not remain constant.

Front

Define proportional relationship.

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

What is a slope in the context of a graph?

Back

The slope is a measure of the steepness of a line on a graph, calculated as the rise over run (change in y over change in x).

Front

How do you determine if a relationship is linear?

Back

A relationship is linear if it can be represented by a straight line on a graph, meaning it has a constant rate of change.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for finding the slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What does it mean for a table to be proportional?

Back

A table is proportional if all pairs of values maintain a constant ratio, meaning the relationship can be expressed as y = kx.
