Finding x and y intercepts

Front

What are the x- and y- intercepts on a graph?

Back

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

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

Back

To find the x-intercept, set y=0 in the equation and solve for x.

Front

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

Back

To find the y-intercept, set x=0 in the equation and solve for y.

Front

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

Back

The ordered pair for the y-intercept is (0, y), where y is the value of the function when x=0.

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

Back

The ordered pair for the x-intercept is (x, 0), where x is the value of the function when y=0.

Front

If a line has an x-intercept of (4, 0), what does this mean?

Back

It means that the line crosses the x-axis at the point (4, 0).

Front

If a line has a y-intercept of (0, 3), what does this mean?

Back

It means that the line crosses the y-axis at the point (0, 3).

Front

What is the significance of intercepts in graphing linear equations?

Back

Intercepts help to quickly identify key points on the graph, making it easier to sketch the line.

Front

What does it mean if a line has no x-intercept?

Back

It means the line is parallel to the x-axis and does not cross it.

What does it mean if a line has no y-intercept?

Back

It means the line is parallel to the y-axis and does not cross it.
