#1 B. 12 Units
#2
Step-by-step explanation:
For number one it is just adding 5 and 7 together because they both have the same X axis, for number two we have to use the distance formula like this:
d= (x2 - x1)^2 + (y2 - y1)^2
d= (-3 - 2)^2 + (5 - -6)^2
d= (-5)^2 + (-11)^2
d= 25 + 121
d= 146 = 1.46
For 3 through 5 it is the same thing as number 2
