What is the Range of a linear function?

Back

The range of a linear function is the set of all possible output values (y-values) that the function can produce. For example, for the function defined by the equation y = mx + b, the range can be all real numbers if m is not zero.

What is a linear function?

Back

A linear function is a function that can be graphically represented in the coordinate plane as a straight line. It has the form y = mx + b, where m is the slope and b is the y-intercept.

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 over run). It is often represented by the letter m.

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented by the value of b in the linear equation y = mx + b.

How do you add fractions with different denominators?

Back

To add fractions with different denominators, find a common denominator, convert each fraction to an equivalent fraction with that denominator, and then add the numerators.

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.
