Use the distance formula.
d = √[(x1 - x2)2 + (y1 - y2)2]
d = 5
x1 = 0
x2 = 3
y1 = 0
y2 = ?
√[(0 - 3)2 + (0 - y2)2] = 5
25 = 9 + y22
y2 = √16 = ±4
There are 2 points that meet these criteria: (3,4) and (3,-4). Test the answers.

That works too, substituting h=k=0, x=3, r=5, and solving for y.

I got the same answer but I used the formula: (x-h)2 +(y-k)2=r2 Is this acceptable or no?07/08/23
