x and y intercepts

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, y).

Front

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

Back

To find the y-intercept, look for the point where the line intersects the y-axis.

Front

What is the x-intercept?

Back

The x-intercept is the point where a line crosses the x-axis. It is represented as (x, 0).

Front

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

Back

To find the x-intercept, look for the point where the line intersects the x-axis.

Front

What does the point (0, -1) represent?

Back

The point (0, -1) represents the y-intercept of a line.

Front

What does the point (4, 0) represent?

Back

The point (4, 0) represents the x-intercept of a line.

Front

If a line has a y-intercept of -1, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -1).

Front

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

Back

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

Front

What is the significance of intercepts in graphing?

Back

Intercepts help to determine the position of the line on the graph and are key points for sketching the line.

Front

How can you determine the y-intercept from an equation?

Back

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