Question

Using the points B (4, -8) and C (-2,4) find the midpoint and distance

Answer 1

Mid point :

`( (x_(1) +x_(2))/(2) ) , ( (y_(1) +y_(2))/(2) )\\((4-2)/(2)), ((-8+4)/(2))\\ (1,-2)`

Distance

`\sqrt{(x_(2) -x_(1) )^(2)} + \sqrt{(y_(2) -y_(1) )^(2)}\\\sqrt{(-2 -4 )^(2)} + \sqrt{(4 -(-8) )^(2)}\\\\√(36)+√(144)\\\\ 6+12\\ 18`
