How to solve multi-step equations
To solve an equation, find every value that makes both sides equal. Simplify each side, gather variable terms, and use inverse operations on both sides. Substitution into the original equation checks the result.

Function notation: what f(x) means
f(x) means the output of a function f when its input is x. The parentheses identify an input; they do not mean f multiplied by x. To evaluate a formula, replace every occurrence of the input variable.
Slope-intercept form from equations and tables
The equation y = mx + b describes a nonvertical line. Its slope m is the change in y for each one-unit increase in x, and b is the y-value where the line crosses the y-axis.
