## Understanding slope of a line

Illustrate the slope of the given line.

What does the slope of a line represent?

How is slope of a line calculated?

What would be an example of using slope in the real world?

## Draw a line that has a positive slope, a line that has a negative slope, a line that has a slope of zero, and a line that has an undefined slope.

What is the equation of the line that has the positive slope. Write equation in slope intercept form.

What is the equation of the line that has the negative slope. Write equation in slope intercept form.

What is the equation of the line that has a slope of zero.

What is the equation of the line that has an undefined slope?

## Draw two lines that are parallel. Draw two lines that are perpendicular.

How do the slopes of parallel lines compare? How to the slopes of perpendicular lines compare?
