ROC/SLOPE (Graphs & Tables)

Front

What is the formula to calculate slope using a graph?

Back

Slope = rise over run.

Front

How do you find the slope from a table of values?

Back

Calculate the change in y (rise) divided by the change in x (run) between two points.

Front

What does a positive slope indicate about a graph?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a graph?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line rises from left to right, what can you say about its slope?

Back

The slope is positive.

Front

If a line falls from left to right, what can you say about its slope?

Back

The slope is negative.

Front

How do you interpret a slope of 1/2?

Back

For every 2 units you move right, the line rises 1 unit.

Front

How do you interpret a slope of -3/4?

Back

For every 4 units you move right, the line falls 3 units.
