To find the 2 points with the same y-coordinates as B, they have to be on the same level as B
That means their y-coordinates must be 3
(x1, 3) and (x2, 3)
The distance between then and B is 6 units, then we will add and subtract 6 from the x-coordinate of B
Since the x-coordinate of B is 1, then
x1 = 1 - 6 = -5
x2 = 1 + 6 = 7
The 2 points are (-5, 3) and (7, 3)
