Grace has a 45 degree upwards angle, then the height of the lighthouse is 14'.
Case A. Kelly is 26 feet from the lighthouse.
The arcTangent of 14/26 is a 28.3 degree angle.
Case B. But if Kelly stood closer to the lighthouse, i.e. 2 feet away, then her angle is arcTangent of 14/2 = 81.9 degrees
In a symmetrical distribution mean=median=mode, so the median could be 28

Answer:
D'(2, -1)
Step-by-step explanation:
Dilation about the origin by factor k multiplies each coordinate by that factor:
(x, y) ⇒ (kx, ky)
For k = 1/3, this is ...
(x, y) ⇒ (x/3, y/3)
D(6, -3) ⇒ D'(6/3, -3/3) = D'(2, -1)
Y = -2x + 4
6x + 3y = 6x + 3(-2x + 4) = 6x - 6x + 12 = 12
⇒ y = -2x + 4 == 6x + 3y = 12 ⇒ invinite solutions: 12
⇒ no solutions -12, -4, 0, 4
