Question

Find the distance between the points ( – 4,10) and (8,10).

Answer 1

12 units

Explanation:

(-4 , 10) ;
`x_(1) = -4` and
`y_(1) = 10`

(8 ,10) ;
`x_(2) = 8` and
`y_(2)= 10`

Distance =
`\sqrt{(x_(2)-x_(1))^(2)+(y_(2)-y_(1))^(2)}`

`= \sqrt{(8-[-4])^(2)+(10-10)^(2)}\\\\=\sqrt{(8+4)^(2)+0}\\\\= \sqrt{12^(2)}\\\\= 12 units`
