What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input. In other words, for every x-value, there is one and only one y-value.

Identify the characteristics of a function using ordered pairs.

Back

A set of ordered pairs represents a function if no two pairs have the same first element (x-value).

Front

Solve for x: x + 2y = -3 and x - y = -12.

Back

x = -9.

Front

What does a correlation coefficient close to 0 indicate?

Back

It indicates a weak or no linear relationship between the variables.

Front

How do you determine if a point is part of the solution set for a system of inequalities?

Back

Substitute the point into each inequality. If it satisfies all inequalities, it is part of the solution set.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

What does the graph of y < 2x + 3 represent?

Back

It represents all the points (x, y) that lie below the line y = 2x + 3.

Front

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

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

What is the difference between independent and dependent variables?

Back

The independent variable is the one that is changed or controlled in an experiment, while the dependent variable is the one that is measured or affected.
