The values of y are 1 and 3
What is distance formula -
x1 and y1 are x and y coordinates of a point.
similarly x2 and y2 are x and y coordinates of another point.
Explanation with steps -
As point P is equidistant from Q and R, the distances PQ and PR should be the same.
So, calculate distance PQ can be calculated from the above formula
The distance PQ is
now use this distance to calculate the unkown 'y'
Squaring both sides
50 = 49 +
On factorizing,
Thus we get values of y to be 1 or 3
