Identifying x and y-intercepts from a graph

Front

What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis. At this point, the value of y is 0.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis. At this point, the value of x is 0.

Front

How do you find the x-intercept from a graph?

Back

To find the x-intercept, look for the point where the graph touches or crosses the x-axis.

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept, look for the point where the graph touches or crosses the y-axis.

Front

What is the ordered pair for the x-intercept if the graph crosses at (-3,0)?

Back

The ordered pair for the x-intercept is (-3,0).

Front

What is the ordered pair for the y-intercept if the graph crosses at (0,-2)?

Back

The ordered pair for the y-intercept is (0,-2).

Front

If a graph has an x-intercept at -3, what does this indicate?

Back

It indicates that the graph crosses the x-axis at the point (-3,0).

Front

If a graph has a y-intercept at -2, what does this indicate?

Back

It indicates that the graph crosses the y-axis at the point (0,-2).

Front

What is the significance of intercepts in graphing?

Back

Intercepts help to identify key points on the graph and can assist in sketching the graph accurately.

Front

Can a graph have more than one x-intercept?

Back

Yes, a graph can have multiple x-intercepts, especially in polynomial functions.
