Key Concepts

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

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.
