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

Back

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

Front

What does it mean for a relation to be a function?

Back

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

Front

How do you determine if a 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

What is the order of operations in mathematics?

Back

The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.

Front

Simplify the expression: 3x^2 - x + 7 + 5x + 2 - 2x^2

Back

x^2 + 4x + 9.

Front

What is the value of (7 + 41) ÷ 2 – 15?

Back

9.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is the y-intercept of the function y = -x + 4?

Back

The y-intercept is 4, which is the point where the line crosses the y-axis.

Front

What does it mean for an expression to be simplified?

Back

To simplify an expression means to reduce it to its simplest form, combining like terms and eliminating unnecessary parts.

Front

What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables, coefficients, and non-negative integer exponents.
