What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1. This means that one line is the negative reciprocal of the other.

What is the difference between dependent and independent variables?

Back

The independent variable is the variable that is manipulated or changed (usually x), while the dependent variable is the variable that is measured or affected (usually y).
