Moving from a to b, the x component of the desired vector is 7-(-9) = 16, and
the y component is 3-9 = -6.
So the vector from a to b is <16,-6>, and the magnitude is
sqrt(16^2 + (-6)^2 ), applying the Pythagorean Theorem.
Answer:sum =378 according to your new questions.
to find average temperature
use formula
average =sum of temperature /no of measuring day
=378/9=42 is your answer
