Front

How do you find the zero of a linear function?

Back

Set the function equal to zero and solve for x.

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

If a linear function has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a linear function has a negative slope, what does that indicate about the line?

Back
