1. Answer:

   we have given

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

   distance is 10 units so

   [tex]d = \sqrt{(xcom. {)}^{2} | } + (ycom. {)}^{2} [/tex]

   [tex](10 {) }^{2} = (10 – 2 {)}^{2} + (y – 3 {)}^{2} [/tex]

   [tex]100 = 64 + (y – 3 {)}^{2} [/tex]

   [tex] \sqrt{(100 – 64) } \: \: \: \: \: = y – 3[/tex]

   [tex]6 + 3 = y[/tex]

   [tex]y \: = 9[/tex]
