Lesson 3.3 Comparing Slope & Unit Rate

Front

What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the rise over the run. In this case, the slope is 2.

Front

Find the slope of the line represented by the points (1, 2) and (4, 8).

Back

The slope is 4/3.

Front

What are the missing numbers in the table showing the relationship between ginger ale and fruit juice for fruit punch?

Back

The missing numbers are 2 & 54.

Front

What is the unit rate for the given table?

Back

The unit rate is $9 per hour.

Front

Define unit rate.

Back

A unit rate is a rate in which the second quantity in the comparison is one unit.

Front

What is the formula for calculating slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

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

Back

A slope of 0 indicates a horizontal line.

Front

If a line has an undefined slope, what does that indicate?

Back

An undefined slope indicates a vertical line.

Front

What is the relationship between slope and unit rate?

Back

The slope of a line represents the unit rate of change between two quantities.

Front

How do you interpret a slope of 3?

Back

A slope of 3 means that for every 1 unit increase in x, y increases by 3 units.
