Algebra 1 Semester 1 Review

Front

Which graph represents a function?

Back

Use the Vertical Line Test: If a vertical line intersects the graph at more than one point, it is not a function.

Front

Identify the property: a + 0 = a

Back

Identity of Addition: Adding zero to a number does not change its value.

Front

1/x * 12 = 12

Back

Identity Property of Multiplication: Any number multiplied by 1 remains unchanged.

Front

For the equation y - 3 = 2(x + 4), what is the slope?

Back

The slope is 2.

Front

Define Symmetric Property

Back

If a = b, then b = a.

Front

What is the Commutative Property of Addition?

Back

a + b = b + a: The order of addition does not affect the sum.

Front

What is the Distributive Property?

Back

a(b + c) = ab + ac: Multiplying a number by a sum is the same as multiplying each addend by the number.

Front

What is the Inverse Property of Addition?

Back

a + (-a) = 0: A number plus its opposite equals zero.

Front

What is the definition of a linear function?

Back

A function that graphs to a straight line, typically in the form y = mx + b.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.
