Front

What does the slope represent in a real-world context?

Back

The slope represents the rate of change or how much y changes for a unit change in x.

Front

If the slope is 15 sit-ups per day, what does this mean?

Back

It means that for each day, the number of sit-ups increases by 15.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

In the equation y = mx + b, what does 'b' represent?

Back

The 'b' represents the y-intercept of the line.

Front

How can you determine the slope from a graph?

Back

The slope can be determined by finding the rise over run between two points on the line.
