Graphing Points and Reflections

The video tutorial explains how to plot points on a coordinate plane and reflect them across the Y-axis. It begins by introducing the points (3,4) and (-3,4), and demonstrates how to plot them using the x and y coordinates. The tutorial then shows how these points are reflected across the Y-axis, highlighting the symmetry involved in this process.

What are the coordinates of the points discussed in the introduction?

• (4, -3) and (-4, -3)

• (3, 4) and (-3, 4)

• (4, 3) and (-4, 3)

• (3, -4) and (-3, -4)

When plotting the point (3, 4), which axis do you move along first?

• Diagonal

• Y-axis

• X-axis

• Z-axis

How many units do you move up to plot the point (3, 4) after moving along the X-axis?

• 3 units

• 4 units

• 5 units

• 6 units

For the point (-3, 4), in which direction do you move along the X-axis?

• Right

• Down

• Up

• Left

What is the Y-coordinate for both points (3, 4) and (-3, 4)?

• -4

• -3

• 3

• 4

Which axis do the points (3, 4) and (-3, 4) reflect across?

• X-axis

• Y-axis

• Diagonal

• Z-axis

If a point is reflected over the Y-axis, what happens to its X-coordinate?

• It doubles

• It remains the same

• It becomes negative

• It becomes positive
