The mid-point of the straight line joining A(4,-3), B(6,-2) is located at C.

(a) Calculate the coordinates of C.

(b) Verify your result by calculating the distances AC and BC and showing they are equal.

I HAVE COMPLETED A BUT CAN'T DO DO B!!!!

try to use distance formula, then compare their distance

Do I have to do part a too ?

-2 + -3 = -5
-5/2 = -2.5 which is y of C

4 ) 6 = 10
10/5 = 5 which is x of C
so
C(5, -2.5)

now AC
dx = 5-4 = 1
dy = -2.5 - -3 = .5
d^2 = 1+.25

now CB
dx = 6 -5 = 1
dy = -2 - -2.5 = .5
d^2 = 1 + .25 the same
