Proportion/Slope Review

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

What is the slope of a line?

Back

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

Front

How do you find the unit rate from a proportional relationship?

Back

The unit rate is found by dividing the total amount by the number of units, giving the amount per one unit.

Front

What does it mean for a graph to be proportional?

Back

A graph is proportional if it passes through the origin (0,0) and forms a straight line.

Front

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

Back

Front

If a line has a slope of 2, what does this mean?

Back

A slope of 2 means that for every 1 unit increase in x, y increases by 2 units.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio and pass through the origin, while non-proportional relationships do not.

Front

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

Back

If the ratios of corresponding values are constant, the relationship is proportional.

Front

What does a straight line on a graph indicate about the relationship between x and y?

Back

A straight line indicates a linear relationship, which can be proportional or non-proportional depending on whether it passes through the origin.

Front

What is the significance of the y-intercept in a linear equation?

Back

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