Question

Find the distance between two points A ( 1 , 4 ) and B ( 7, 12 )

Distance (d)^2 = ( X2 -X1 ) ^2 + ( Y2 - Y1 )^2











Find The Midpoint of P ( 4 , 4 ) and Q ( 6, 8 )


Midpoint ( M ) = ( x1 + x2 / 2 , y1 + y2 / 2

Answer 1

d^2= (7-1)^2 + (12-4)^2

d^2= 6^2+8^2= 36+64= 100

d=\sqrt{100} = 10

M= ((4+6)/2, (4+8)/2)

M= (5, 6)
