What is the purpose of solving an equation?

Back

To find the value(s) of the variable(s) that make the equation true.

Front

What does it mean to simplify an expression?

Back

To reduce an expression to its simplest form by combining like terms and performing operations.

Front

What is a linear equation?

Back

An equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

How do you find the slope of a line given two points?

Back

Use the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What are like terms?

Back

Terms in an expression that have the same variable raised to the same power.

Front

What is the distributive property?

Back

A property that states a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside parentheses.

Front

What is a quadratic equation?

Back

An equation that can be expressed in the form ax^2 + bx + c = 0, where a, b, and c are constants.
