Question

A triangle has vertices at S(1, 1), T(2, -3), and U(4, 0). The triangle is translated up 3 units. What are the coordinates of the vertices of the image?

Answer 1

To translate the triangle up 3 units, we add 3 to the y-coordinate of each vertex.

The new coordinates of S are (1, 1+3) = (1, 4)

The new coordinates of T are (2, -3+3) = (2, 0)

The new coordinates of U are (4, 0+3) = (4, 3)

Therefore, the vertices of the image are S'(1, 4), T'(2, 0), and U'(4, 3).
