Slope and Constant of Proportionality REVIEW

Front

What is the y-axis?

Back

The vertical axis on a graph, used to represent the dependent variable.

Front

What is the slope of a line?

Back

The measure of the steepness of a line, calculated as the rise over run.

Front

How do you find the slope of a line?

Back

By using the formula: Slope = Rise/Run.

Front

What is the x-axis?

Back

The horizontal axis on a graph, used to represent the independent variable.

Front

What does a constant of proportionality represent?

Back

It represents the ratio between two proportional quantities.

Front

If a line has a slope of 4, what does this mean?

Back

For every 1 unit increase in the x-direction, the y-value increases by 4 units.

Front

What is a proportional relationship?

Back

A relationship where two quantities maintain a constant ratio.

Front

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

Back

By checking if the ratios of corresponding values are constant.

Front

What is the constant of proportionality for the relationship represented by the table: (1, 3), (2, 6), (3, 9)?

Back

3, because each y-value is 3 times the x-value.

Front

What does 'rise' refer to in slope calculations?

Back

The vertical change between two points on a line.
