What is the formula for the area of a rectangle?

Back

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

Front

How do you express the area of a rectangle in terms of its dimensions?

Back

The area can be expressed as a product of its dimensions: Area = (length)(width).

Front

What is the domain of a function?

Back

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

Front

How do you find the domain of a function given its graph?

Back

To find the domain from a graph, identify the x-values for which the graph exists. For example, if the graph is defined from -7 to 7, the domain is [-7, 7].

Front

What is symmetry in graphs?

Back

Symmetry in graphs refers to a situation where one half of the graph is a mirror image of the other half.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a figure into two mirror-image halves.

Front

How do you write an equation for a linear function?

Back

A linear function can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the y-intercept of a linear equation?

Back

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

Front

What is a function?

Back

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