What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, greater than or equal to, or less than or equal to the other.

Front

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

Back

A relation is a function if each input (x-value) is paired with exactly one output (y-value).

Front

What is slope-intercept form?

Back

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

Front

How do you convert an equation to slope-intercept form?

Back

To convert an equation to slope-intercept form, solve for y in terms of x.

Front

What is scientific notation?

Back

Scientific notation is a way of expressing numbers as a product of a number between 1 and 10 and a power of 10.

Front

How do you identify a function from a set of ordered pairs?

Back

A set of ordered pairs represents a function if no x-value is repeated with a different y-value.

Front

What is the slope of a line?

Back

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

Front

What does the term 'y-intercept' refer to?

Back

The y-intercept is the point where a line crosses the y-axis, represented by the value of y when x = 0.

Front

What is the difference between a linear equation and a nonlinear equation?

Back

A linear equation graphs as a straight line, while a nonlinear equation graphs as a curve.

Front

What is the purpose of graphing inequalities?

Back

Graphing inequalities helps visualize the set of solutions that satisfy the inequality.
