Find the distance d(P1,P2) between the points P1 and P2.

P1= (-2,1); P2= (0,0)
P1= (-1,1); P2= (2,2)
P1= (-1,0); P2= (2,4)
P1= (2,-3); P2= (4,2)

    You should know the distance formula

    I will do the 2nd, you do the others

    Distance = √( 2-(-1))^2 + (2-1)^2 )
    = √( 3^2 + 1^2)
    = √(9+1)
    = √10
