Question

What are the coordinates of point X? (1,3) (3, -1) (3,1) (-1, -3)

Answer 1

I believe it’s (-3,1) because you count 3 going left starting at the point 0. And since the X-int on the left side is negative that’s why it’s -3. Then you just go up 1 time .

Answer 2

The rule for 90 degrees clockwise is
(x, y) to (y, -x)

So it would be (1, 3)
