Question

find the midpoint of AB whose endpoints are A(37,-70)and B(53,-102)

Answer 1

the midpoint is like the average of the x's and the y's\[x _{m}=\frac{37+53}{2}=45\]\[y _{m}=\frac{-70-102}{2}=-86\]the midpoint is (45, -86)

Answer 2

isn't it 86 not -86

Answer 3

it should be -86 based on the negative y-coordinates of the given endpoints

Answer 4

here is a rough sketch; it shows the negative y-coordinate of the midpoint
