Answer:
Neither A or B
Step-by-step explanation:
Hello There!
In order for a set of ordered pairs to represent a function none of the x values can repeat
In answer choice A the x value 7 repeats therefore the set of ordered pairs do not represent a function
In answer choice B the x value 7 repeats therefore the set of ordered pairs do not represent a function
so we can conclude that neither set of ordered pairs represent a function

Answer:
(-1/2,5)
Step-by-step explanation:
Here is the complete question
Find the midpoint of the segment with endpoints of (1, 4) and (-2, 6) and enter its coordinates as an ordered pair. If necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.
Solution
The mid-point of a line is given by ((x₁ + x₂)/2,(y₁ + y₂)/2). From the question, x₁ = 1, y₁ = 4, x₂ = -2 and y₂ = 6. So,
((x₁ + x₂)/2,(y₁ + y₂)/2) = ((1 + (-2))/2,(4 + 6)/2)
= ((1 - 2)/2,10/2)
= (-1/2,10/2)
= (-1/2,5)
