Front

Which graph does NOT pass the vertical line test?

Back

Graph 1

Front

Back

Nonlinear since it is NOT in slope intercept form (y=mx+b)

Front

Back

Linear since it is in slope-intercept form (y=mx+b)

Front

Is the function linear or nonlinear if there is a constant rate of change?

Back

Linear since there is a constant rate of change

Front

What is the definition of a linear function?

Back

A function that can be graphically represented as a straight line.

Front

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

Back

Front

What does the vertical line test determine?

Back

It determines if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a nonlinear function?

Back

A function that does not create a straight line when graphed.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function.
