Unit 2 Test

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning it does not have a defined angle of inclination.

Front

How do you calculate 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 the significance of a positive slope in a linear function?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship.

Front

What does a negative slope indicate about the relationship between x and y?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing an inverse relationship.

Front

In the context of a linear equation, what does the term 'rate of change' refer to?

Back

The rate of change refers to how much the dependent variable (y) changes for a unit change in the independent variable (x), represented by the slope.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you represent a linear relationship graphically?

Back

A linear relationship can be represented graphically as a straight line on a coordinate plane.

Front

What is the meaning of the term 'domain' in 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

What is the meaning of the term 'range' in a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.
