Sem. Exam Review 2 - D&R, Slopes, Intercepts, HOYVUX

Front

What are the x and y intercepts of a linear function?

Back

The x-intercept is the point where the graph crosses the x-axis (y=0), and the y-intercept is where it crosses the y-axis (x=0).

Front

How do you find the x-intercept of a linear equation?

Back

Set y=0 in the equation and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

Set x=0 in the equation and solve for y.

Front

What is the slope of a line?

Back

The slope (m) is a measure of the steepness of a line, calculated as the change in y over the change in x (rise/run).

Front

Back

The slope is 2.

Front

What is the range of a function?

Back

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

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 does HOYVUX stand for?

Back

HOYVUX is a mnemonic for remembering that horizontal lines have a slope of 0 (y=constant) and vertical lines have an undefined slope (x=constant).

Front

Back

The x-intercept is (-2, 0).

Front

Back

The y-intercept is (0, 1).
