If the representation is a graph then use the vertical line test. Draw or imagine straight vertical lines going down the graph. If the vertical line only goes through the function line one time then it is a function. For an example, a circle on a coordinate plane is not a function but a wavy line is.
If the representation is a table with points then look at the x values. If x repeats then it is not a function.
Answer:
You can use the midpoint formula.
Method:
MAB = (Ax+Bx)/2 ; (Ay+By)/2
Substitute in what you have:
(2;4) = (Ax+3)/2 ; (Ay+7)/2
Because we know the x coordinate of the midpoint, we can assume that:
2 = (Ax+3)/2
And now solve for Ax:
4 = Ax+3
Ax = 1
Because we know the y coordinate of the midpoint, we can assume that:
4 = (Ay+7)/2
And now solve for Ay:
8 = Ay+7
Ay = 1
Therefore A(1;1)
