What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

Identify the equation that represents a proportional relationship: y = 1/2x - 1/2, y = 1/2x, y = 2x - 2, y = 2x + 2.

Back

y = 1/2x

Front

Does the graph of a proportional relationship pass through the origin?

Back

Yes, the graph of a proportional relationship always passes through the origin (0,0).

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line is decreasing as it moves from left to right.

If a line has a slope of 4/5, what does this mean?

Back

For every 5 units the line moves horizontally, it moves up 4 units vertically.
