What is the Commutative Property of Multiplication?

Back

The Commutative Property of Multiplication states that changing the order of the factors does not change the product. For example, 12 x 2 = 2 x 12.

Front

What are the x values or inputs in a function called?

Back

The x values or inputs in a function are called the Domain.

Front

How do you find the slope of a line?

Back

The slope of a line is calculated as the change in y divided by the change in x (rise over run). For example, if the slope is 4, it means for every 4 units you move up, you move 1 unit to the right.

Front

Evaluate 9a - ab + 5b if a = 2 and b = 7.

Back

The evaluation gives 39.

Front

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

Back

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

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x).

Front

What is the Range in a function?

Back

The Range is the set of all possible output values (y) of a function.

Front

What does it mean for two numbers to be additive inverses?

Back

Two numbers are additive inverses if their sum is zero. For example, 5 and -5 are additive inverses.

Front

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The formula for the slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum.
