If x is at (4,3) what would be the coordinates of x' if you translated 4 units right and 8 units up? (-3,7) (8,11) (0,-4)

Since going toward the right means an increasing x-coordinate, this means that x = 4, moved 4 units to the right, would become x = 8.
Similarly, since going up means an increasing y-coordinate, this means that y = 3, moved 8 units upward, would become y = 11.

Therefore, the final location would be at x = 8, y = 11, or at (8, 11).

The answer is: a = about 63.59ft2 for 15
