Triangle ABC is reflected across the x-axis. If the coordinates of the original shape are A(−4,−1), B(−5,−2), and C(−10,−1), what are the coordinates of A′, B′, and C′?(1 point)

Answer 1

The reflection across the x-axis will change the signs of the y-coordinates while leaving the x-coordinates unchanged.

So the new coordinates are:
A'(-4, 1)
B'(-5, 2)
C'(-10, 1)

Answer 2

friend produced a reflection over the y-axis that looks like this figure. You notice a problem with the reflection. How would you suggest correcting the reflection?

Shift the reflected figure 1 unit to the left.
Shift the reflected figure 1 unit up.
Shift the reflected figure 1 unit down.
• Shift the reflected figure 1 unit to the right.
