Key Concepts

• A linear equation can be in the form $y=mx+b$, where $y$ is the dependent variable and $x$ is the independent variable.
• The slope of a linear equation is $m$ and the $y$-intercept of a linear equation is $b$.

Glossary

Dependent variable: the variable on the y-axis, the value of the variable on the y-axis depends on a specific value of the independent variable.

Independent variable: the variable on the x-axis, the value of a dependent variable is predicted based on the value of the independent variable.
