You can put this solution on YOUR website!
A(-5, 0),
B(-2, 0),
C(0,+-3),
D(0,+-y),

distance OA=5+units left
distance OB=+2units left
distance OC=+3units down
distance OD=+y units down
distance OA%2FOB=+OC%2FOD => 5%2F2=3%2Fy => 5y=6=>+y=1.2 units down, means y coordinate is -1.2
or this way:
-5%2F-2=-3%2Fy
-5y=-3%28-2%29%0D%0A%7B%7B%7B-5y=6
y=6%2F-5
y=-1.2
so, answer is: D(0, -1.2)
