What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, some quantity. In geometry, it is used to determine how much a figure is enlarged or reduced.

Front

What does it mean if a scale factor is greater than 1?

Back

If a scale factor is greater than 1, it indicates an enlargement of the figure.

Front

What does it mean if a scale factor is less than 1?

Back

If a scale factor is less than 1, it indicates a reduction of the figure.

Front

How do you find the range of a set of numbers?

Back

The range is found by subtracting the smallest number in the set from the largest number.

Front

What is the range of the set {-5, -2, 1, 4}?

Back

The range is 4 - (-5) = 9.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for a function.

Front

What is the domain of the set {-4, -1, 0, 2, 7}?

Back

The domain is the set itself: {-4, -1, 0, 2, 7}.

Front

What is slope-intercept form of a linear equation?

Back

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

Front

Convert the equation -10x + y = 3 to slope-intercept form.

Back

y = 10x + 3.

Front

What is the slope in the equation y = 10x + 3?

Back

The slope (m) is 10.
