Unit 5: Slope and Proportional Review

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line. It is calculated as the change in y divided by the change in x (rise over run).

Front

How do you determine if a relationship is proportional?

Back

A relationship is proportional if the ratio of y to x is constant. This means that as x increases or decreases, y changes at a consistent rate.

What is the equation of a line in slope-intercept form?

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning it goes straight up and down.

If a line has a slope of -5/3, what does this tell you about its direction?

Back

A slope of -5/3 indicates that the line descends from left to right.

What is the graphical representation of a proportional relationship?

Back

The graphical representation of a proportional relationship is a straight line that passes through the origin (0,0).
