What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is a variable in algebra?

Back

A variable is a symbol, usually a letter, that represents one or more numbers. For example, in the expression x + 2, x is a variable.

Front

What does it mean to solve an equation?

Back

To solve an equation means to find the value of the variable that makes the equation true. For example, in the equation x + 3 = 7, solving gives x = 4.

Front

What is a coefficient?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 4x, 4 is the coefficient.

Front

What is a constant in algebra?

Back

A constant is a fixed value that does not change. For example, in the expression 3x + 5, the number 5 is a constant.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line. It is calculated as the rise over run.

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. In the equation y = mx + b, 'b' represents the y-intercept.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. For example, f(x) = 2x + 3 is a function.
