The triangle is translated 2 units left and 4 units up. What are the coordinates of the vertices of △J′K′L′, the translated triangle?

Answer 1

To translate a point in the coordinate plane, you need to add (or subtract) the same amounts from the x-coordinate and y-coordinate of the original point.

If the triangle's vertices are J(x, y), K(x, y) and L(x, y), then the coordinates of the translated vertices △J'K'L' would be:

J' = (x - 2, y + 4)
K' = (x - 2, y + 4)
L' = (x - 2, y + 4)
