Answer:
C) 1 and III only
Step-by-step explanation:
Answer: 
Step-by-step explanation:
The line passes through (-1, 0) and (3,2), so the gradient is
.
This means the equation of the line is of the form
for some constant c.
Substituting in the coordinates of the point (-1,0),

Thus, the equation of the line is 
The answer is B that's what I got. Note: Anytime it says per just know that it's going to have a variable with it. :)
Parameterize
by
with
and
. Then the surface element is

so that the integral is

the one to the left is 6x + 2y
the one in the middle is 5x
the one on the right is 3x + y
