Front

What is the definition of slope?

Back

The slope of a line is the ratio of the rise (change in y) to the run (change in x).

Front

What does an open circle represent on a number line?

Back

An open circle indicates that the number is not included in the solution set.

Front

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

Back

Slope = \frac{y2 - y1}{x2 - x1}

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a filled circle represent on a number line?

Back

A filled circle indicates that the number is included in the solution set.
