I really need your help! - Thank You
1) Find the distance (d) and Midpoint (M) for the two given points: P=(1, 7) & Q =(-3, 10). *
A) d = 5 and M = (-1, 8.5)
B) d = 10 & M =( 3,10)
C) d = 6 & M = (-1,3)
D) d = 9 & M =(10,3)

2) Find the Distance and Midpoint of PQ: P =(2,7) & Q = (10,13) *
A) d = 8 & M =(-6,10)
B) d = -10 & M = (10,6)
C) d = 10 & M = (6, 10)
D) d = 12 & M =(5,12)

3) What is the radius (r) and center of the circle x^2 + y^2 = 81?
A) r = 9 and C= (0,0)
B) r = 81 and C = (0,0)
C) r = 2 and C = (0,0)
D) r = 81 and C= (1,2)

4) What is the radius (r) and center (C) of the circle (x-1)^2 + (y+2)^2 = 16? *
r = 4, and C = (0,0)
B) r = 16, and (0,0)
r = 4 and C =(1, -2)
D) r = 4 and C = ( 1,2)
