Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is and the direction it goes (positive or negative).

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts. They will never intersect.

How do you determine the equation of a line from a table of values?

Back

Identify two points from the table, calculate the slope using those points, and then use one of the points to write the equation in slope-intercept form.
