Proportional Relationships Module 1 Review

Front

What is a proportional relationship?

Back

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

Front

How can you tell if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratios of the corresponding values are equal.

Front

What does the slope (m) represent in the equation y = mx?

Back

The slope (m) represents the rate of change between the dependent and independent variables.

Front

What is the ordered pair for point A if A is at (2, 0)?

Back

The ordered pair for point A is (2, 0).

Front

If a table shows the values (1, 2), (2, 4), (3, 6), does it represent a proportional relationship?

Back

Yes, it represents a proportional relationship because the ratios (y/x) are constant (2).

Front

What is the constant rate of change (slope) if the points are (1, 2) and (3, 6)?

Back

The slope is 2, calculated as (6-2)/(3-1).

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the value of y when x is 0, indicating where the line crosses the y-axis.

Front

If y = 3x, what is the slope?

Back

The slope is 3.

Front

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

Back

The formula is m = (y2 - y1) / (x2 - x1).

Front

Does the equation y = 2x + 1 represent a proportional relationship?

Back

No, because of the +1, which indicates a y-intercept.
