Find the values of y for which the distance between the points P (2, – 3) and Q (10, y) is 10 units.

##### Solution :-

Given: Distance between (2, – 3) and (10, y) is 10.

Using distance formula,

Simplify the above equation and find the value of y.

Squaring both sides,

64 + (y + 3)2 = 100

(y + 3)= 36

y + 3 = ±6

y + 3 = +6 or y + 3 = −6

y = 6 – 3 = 3 or y = – 6 – 3 = -9

Therefore, y = 3 or -9
