How can you identify a linear function from a table?

Back

A linear function will have a constant difference in the y-values for equal differences in the x-values.

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is 0.

Front

How do you determine if a function is linear or nonlinear from a graph?

Back

If the graph is a straight line, the function is linear; if it curves, the function is nonlinear.
