Definition: Rewriting an equation

Back

The process of manipulating an equation to isolate a variable.

Front

Principle: Isolating a variable

Back

To solve for a variable, rearrange the equation to get that variable on one side.

Example: Rearranging 3x + 4 = 10 to solve for x

Back

x = (10 - 4) / 3 = 2.

Front

Definition: Linear equation

Back

An equation that makes a straight line when graphed.

Front

Concept: Slope-intercept form

Back

y = mx + b, where m is the slope and b is the y-intercept.
