Why is this function linear? This is a linear function because it does not have a constant rate of change, This is a linear function because it creates a curved line., This is a linear function because it have a constant rate of change., This is a linear function because it's y-intercept is (0,2)

Back

This is a linear function because it have a constant rate of change.

Front

What does it mean for a function to be linear?

Back

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.

Front
