Plotting Points in the Coordinate Plane

The video tutorial covers the basics of the coordinate plane, including the x-axis, y-axis, origin, and quadrants. It explains how to plot points using ordered pairs and identify which quadrant a point is in. The tutorial also covers reflecting points across the x-axis and y-axis, providing examples with both whole numbers and fractions.

What is the point called where the x-axis and y-axis intersect?

• Intersection

• Center

• Origin

• Axis point

Which quadrant is the point (4, -2) located in?

• Quadrant IV

• Quadrant II

• Quadrant III

• Quadrant I

If a point is at (0, 2), which axis does it lie on?

• Does not lie on any axis

• Origin

• y-axis

• x-axis

How do you plot the point (-5, 0) on the coordinate plane?

• 5 down, stay

• 5 up, stay

• 5 right, stay

• 5 left, stay

Where is the point (-5, 0) located?

• In a quadrant

• On the y-axis

• At the origin

• On the x-axis

What happens to a point when it is reflected over the x-axis?

• y-coordinate changes

• No change

• Both coordinates change

• x-coordinate changes

After reflecting the point (4, 0) over the y-axis, what is the new point?

• (-4, 0)

• (4, 0)

• (0, -4)

• (0, 4)

What is the result of reflecting the point (3, 2) first over the x-axis, then over the y-axis?

• (3, -2)

• (-3, -2)

• (-3, 2)

• (3, 2)

How do you reflect a point across the y-axis?

• Change the x-coordinate

• Change the y-coordinate

• Change both coordinates

• No change needed

What is the new location of a point after reflecting (-2.5, 5.5) over the x-axis?

• (-2.5, 5.5)

• (2.5, 5.5)

• (-2.5, -5.5)

• (2.5, -5.5)
