x & y intercepts

Front

What are the x- and y-intercepts?

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 does the point (0, 5) represent on a graph?

Back

It represents the y-intercept, where the graph crosses the y-axis.

Front

What does the point (5, 0) represent on a graph?

Back

It represents the x-intercept, where the graph crosses the x-axis.

Front

If a graph has no x-intercept, what does that indicate?

Back

It indicates that the graph does not cross the x-axis, meaning the function does not have real roots.
