Finding X and Y Intercepts on a Graph

What is an X intercept?

• Where the function crosses the x-axis

• Where the function has a minimum value

• Where the function crosses the y-axis

• Where the function has a maximum value

What is a Y intercept?

• Where the function crosses the y-axis

• Where the function crosses the x-axis

• Where the function has a minimum value

• Where the function has a maximum value

How do you find the X intercept on a graph?

• Find the lowest point on the graph

• Look where the function crosses the y-axis

• Find the highest point on the graph

• Look where the function crosses the x-axis

What are the coordinates of the X intercept in the given example?

• (2, 0)

• (0, -1)

• (0, 2)

• (-3, 0)

What are the coordinates of the Y intercept in the given example?

• (-3, 0)

• (0, 2)

• (0, -1)

• (2, 0)

What is true about the X intercept of a vertical line?

• It is at the point where the line crosses the y-axis

• It is at the point where the line crosses the x-axis

• It is always at (0, 0)

• It does not exist

What is true about the Y intercept of a vertical line?

• It is at the point where the line crosses the y-axis

• It is at the point where the line crosses the x-axis

• It is always at (0, 0)

• It does not exist

What is true about the Y intercept of a horizontal line?

• It does not exist

• It is always at (0, 0)

• It is at the point where the line crosses the y-axis

• It is at the point where the line crosses the x-axis

What is true about the X intercept of a horizontal line?

• It is at the point where the line crosses the x-axis

• It is at the point where the line crosses the y-axis

• It is always at (0, 0)

• It does not exist

Which type of line will always have both X and Y intercepts?

• None of the above

• Lines with a slope

• Horizontal lines

• Vertical lines
