Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

Which of the following does not represent a function? (2, 3), (3, 4), (4, 5), (5, 6) or (2, 1), (2, 2), (2, 3), (2, 4)?

Back

(2, 1), (2, 2), (2, 3), (2, 4) does not represent a function because the input '2' has multiple outputs.

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

What is the Commutative Property?

Back

The Commutative Property states that the order of addition or multiplication does not change the result, e.g., a + b = b + a.

What is the Associative Property?

Back

The Associative Property states that the way numbers are grouped in addition or multiplication does not change the result, e.g., (a + b) + c = a + (b + c).

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

CCSS.8.EE.B.5

Front

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

Back

To find the slope from a table, select two points (x1, y1) and (x2, y2) and use the formula: slope = (y2 - y1) / (x2 - x1).
