Question

a right triangle is a positioned on a coordinate plane, point c is a the origin, the length of leg cb is twice as long as the length of leg ba, which is d units long. what are the coordinates of points b and a?

Answer 1

If BA is d units the CB must be 2d units. B is on the x-axis, 2d units right of C so its coordinates are (2d, 0). A is d units above B at (2d, d).
