What is the general form of a linear inequality?

Back

A linear inequality can be expressed in the form ax + by <, >, ≤, or ≥ c, where a, b, and c are constants.

How do you determine the slope of a line from its equation?

Back

The slope of a line in the slope-intercept form y = mx + b is represented by the coefficient m.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

How can you represent the domain of a function graphically?

Back

The domain of a function can be represented by the set of x-values for which the function is defined.

Front

What is the significance of the inequality symbol in graphing?

Back

The inequality symbol indicates whether the line is included in the solution set (≤ or ≥) or not (< or >).

Front

How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding linear equation as a dashed or solid line, then shade the appropriate region based on the inequality.

Front

What is the relationship between distance, rate, and time?

Back

The relationship can be expressed as Distance = Rate × Time.

Front

If a car travels 280 miles in 7 hours, what is its average speed?

Back

The average speed is 40 miles per hour (280 miles ÷ 7 hours).

Front

How do you solve for distance when given time and speed?

Back

Multiply the speed by the time to find the distance: Distance = Speed × Time.

Front

What does the term 'direct variation' mean?

Back

Direct variation means that two quantities increase or decrease in proportion to each other.
