What is the rate of change in a linear equation?

Back

The rate of change in a linear equation represents the slope, which indicates how much the dependent variable (y) changes for a unit change in the independent variable (x).

Front

What does the letter 'm' represent in the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

How do you determine which line has the greatest slope?

Back

To determine which line has the greatest slope, compare the steepness of the lines; the steeper the line, the greater the slope.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

The slope is 3/2.

Front

If two lines have the same slope, what can be said about their rates of change?

Back

If two lines have the same slope, they have the same rate of change.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and there is no change in y as x changes.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for calculating the slope is (y2 - y1) / (x2 - x1).

Front

How can you compare the costs of two different rental companies?

Back

To compare costs, calculate the price per hour for each company and determine which is lower.

Front

What does it mean if a graph is steeper than another?

Back

A steeper graph indicates a greater rate of change or slope compared to a less steep graph.

Front

In the equation y = 40x, what does the number 40 represent?

Back

In the equation y = 40x, the number 40 represents the weight in pounds per bag.
