Graphing Using Intercepts Review

Front

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function crosses the x-axis. It has a y-value of 0.

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function crosses the y-axis. It has an x-value of 0.

Front

How do you find the x-intercept of the equation 2x - y = 6?

Back

Set y = 0: 2x - 0 = 6, so x = 3. The x-intercept is (3, 0).

Front

How do you find the y-intercept of the equation 2x - y = 6?

Back

Set x = 0: 2(0) - y = 6, so y = -6. The y-intercept is (0, -6).

Front

What is the ordered pair for the x-intercept of a function?

Back

An ordered pair for the x-intercept has the form (a, 0), where 'a' is the x-value.

Front

What is the ordered pair for the y-intercept of a function?

Back

An ordered pair for the y-intercept has the form (0, b), where 'b' is the y-value.

Front

Identify the x-intercept from the options: (0, 4), (4, 4), (4, 0), None of these.

Back

The x-intercept is (4, 0).

Front

Identify the y-intercept from the options: (0, 1/2), (0, 1), (0, -1/2), (0, -1).

Back

The y-intercept is (0, -1).

Front

What are the x- and y-intercepts for the equation y = 2x + 4?

Back

x-intercept: (-2, 0), y-intercept: (0, 4).

Front

What is the significance of the x-intercept in a graph?

Back

The x-intercept indicates where the function's output is zero.
