Multiple Choice

When a point is reflected across the line x = -3, what happens to its x-coordinate?

Multiple Choice

If a point is reflected across the line y = -4, which coordinate will change and how?

• The x-coordinate changes sign

• The y-coordinate changes sign

• The y-coordinate is equidistant from y = -4 on the opposite side
