Unit 2 Review

Front

What is the range of a relation?

Back

The range of a relation is the set of all output values (y-values) that correspond to the input values (x-values) in the relation.

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all input values (x-values) that can be used in the relation.

Front

What does it mean if the slope of a line is undefined?

Back

An undefined slope indicates that the line is vertical, meaning it does not have a defined rise over run.

Front

What is the slope of a line represented by the ratio 4/3?

Back

The slope of the line is 4/3, indicating that for every 3 units moved horizontally, the line moves 4 units vertically.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What does the term 'vertical line' refer to in graphing?

Back

A vertical line is a line that goes straight up and down, having an undefined slope.

Front

What is the significance of the y-intercept in a linear equation?

Back

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

Front

What is the difference between the domain and range of a function?

Back

The domain is the set of all possible input values (x-values), while the range is the set of all possible output values (y-values).
