OK. The point is, we're just going to pick up the rectangle where it is right now, and relocate
The point is, we're just going to pick up the rectangle where it is right now, and relocate
The point is, we’re just going to pick up the rectangle where it is right now, and relocate
it at a new position. And the new position is 4 units right and
2 units down. Well, moving to the left and right is shifting
the x. And up and down is changing the y value. The original position of A is (-4, 6). Going
to the right is increasing the x value, so
4 plus negative 4 is 0, so the new x coordinate of point A is 0. That means we can eliminate
options B, D, and E. Moving down decreases the y value, so we subtract
2 from the original y. 6 -- 2 is 4, so the new y coordinate is 4.
The new location of point A is (0, 4)- option A.
