Question

If the point (3,-4) is dilated by a scale factor of 74 , what are the new coordinates?

Now take the new points and rotated them 180°. What are the new coordinates?

Answer 1

• (-222, 296)

Explanation:

Given point

• (3, -4)

Dilation by a scale factor of 74:

• (x, y) → (74x, 74y)
• (3, -4) → (74*3, 74(-4)) = (222, -296)

Rotation by 180°:

• (x, y) → (-x, -y)
• (222, -296) → (-222, 296)
