What is the Subtraction Property of Equality?

Back

If a = b, then a - c = b - c for any real number c.

Front

What is the Distributive Property?

Back

a(b + c) = ab + ac; it allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

How do you find the slope from a table of values?

Back

Slope (m) = (change in y) / (change in x) between two points.

Front

What does the equation y = mx + b represent?

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

What is the solution to the equation 3(x - 1) = 2x + 9?

Back

x = 12.

Front

What is the Commutative Property?

Back

The order in which two numbers are added or multiplied does not change the sum or product (a + b = b + a, ab = ba).

Front

What is the Associative Property?

Back

The way in which numbers are grouped in addition or multiplication does not change their sum or product ((a + b) + c = a + (b + c)).

Front

What is the Identity Property of Addition?

Back

The sum of any number and zero is that number (a + 0 = a).

Front

What is the Identity Property of Multiplication?

Back

The product of any number and one is that number (a × 1 = a).

Front

What is the Additive Inverse Property?

Back

For every real number a, there exists a number -a such that a + (-a) = 0.
