How do you find the range of a function from a set of ordered pairs?

Back

Identify all the second elements (y-values) in the pairs.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope but different y-intercepts.

Front

What is the slope-intercept form of a linear equation?

Back

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