What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-coordinate with respect to the x-coordinate. It indicates how steep the line is.

If a line has a slope of -1, what does this indicate about its direction?

Back

A slope of -1 indicates that the line descends from left to right, forming a 45-degree angle with the x-axis.

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.
