y1 = (-18 + 19.5959)/2 = 1.5959/2 = 0.79795
y2 =(-18 - 19.5959)/2 = 37.5959/2 = 18.79795
So the answer is 0.7979 and 18.7979
The first equation that we used is the distance between two points: d = sqrt((y2 - y1)^2 + (x2 - x1)^2)
y2 is the value taht we don't know, and X1, Y1, X2 are the values that que question gives us
also the distance is given, 11
