The formula is called the “midpoint formula”. It looks like this
m=(x1+x2)/2 , (y1+y2)/2 where m means midpoint. In your case it looks like this.
m=(x1+x2)/2 , (y1+y2)/2 where m means midpoint. In your case it looks like this.
Hence the correct answer is C) -23
Further explanation:
We have to put the values of m and n into both expression first separately and then multiply the answers.
Given expressions are:
The values are:
Putting the values in expression 1:
Putting the values of m and n in second expression
Multiplying both expressions:
Hence the correct answer is C) -23
