I don't really know if the question is complete but...
y = x -10 can be a solution
so y would be -7 when x is 3
The product is 7/2. Hope that helps

Answer: (-3, 0)</h3>
Explanation:
Point N is at (1,3)
We apply the rule
which will translate the point 4 units to the left and 3 units down.
The old x coordinate x = 1 becomes x-4 = 1-4 = -3
The old y coordinate y = 3 becomes y-3 = 3-3 = 0
The point N(1,3) moves to N ' (-3, 0)
The answer is 134 ft^2
