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 is calculated as the rise over run.

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept (b), plot it on the y-axis, then use the slope (m) to find another point. Draw a straight line through these points.

What is a solution set in the context of inequalities?

Back

The solution set of an inequality is the set of all ordered pairs (x, y) that satisfy the inequality.

How do you determine if a point is a solution to a linear equation?

Back

To determine if a point (x, y) is a solution, substitute the x-value into the equation and see if the resulting y-value matches.
