Question

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

Answer 1

Answer:

we have given

p( 2,3) and q( 10, y)

distance is 10 units so

$d = \sqrt{(xcom. {)}^{2} | } + (ycom. {)}^{2}$

$(10 {) }^{2} = (10 - 2 {)}^{2} + (y - 3 {)}^{2}$

$100 = 64 + (y - 3 {)}^{2}$

$\sqrt{(100 - 64) } \: \: \: \: \: = y - 3$

$6 + 3 = y$

$y \: = 9$
