7.10 Slope Review

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the change in the vertical direction (rise) divided by the change in the horizontal direction (run).

Front

What does it mean if a relationship is proportional?

Back

A proportional relationship means that two quantities increase or decrease at the same rate, represented by a constant ratio.

Front

What is the slope of a line that rises 3 units for every 1 unit it runs?

Back

The slope is 3.

Front

How do you determine if a point lies on a line given by an equation?

Back

Substitute the x-coordinate of the point into the equation and see if the resulting y-coordinate matches the y-coordinate of the point.

Front

What is the slope of the line represented by the equation y = 2x + 1?

Back

The slope is 2.

Front

What does an additive relationship mean?

Back

An additive relationship means that a constant amount is added to one quantity to get another, rather than a constant ratio.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What is the slope of a line that falls 4 units for every 2 units it runs?

Back

The slope is -2.

Front

How can you identify a proportional relationship from a table of values?

Back

If the ratio of the y-values to the x-values is constant, the relationship is proportional.
