The solution to this equation is x=4.6 because 19.32/4.2=4.6
-3.
Coefficients are numbers that have a variable next to it, thus leading it to be -e of the -3x.
Hope this helps!
(x2 subtracted by x1 divided by 2, y2 subtracted by y1 divided by 2) is the midpoint formula.
(2-3/2, 5-6/2)= (-1/2, -1/2) which is the answer/
The answer is a rectangle
is conservative if there is a scalar function 
such that 
. This would require
(or perhaps the last partial derivative should be 4 to match up with the integral?)
From these equations we find
so 
is indeed conservative, and the gradient theorem (a.k.a. fundamental theorem of calculus for line integrals) applies. The value of the line integral depends only the endpoints:
