Answer 2

Answer:

c 1 is the line integral of the following gradient.

Step-by-step explanation:

The line integral of a gradient is the change in the value of the gradient from point A to Point B.

$\int\limits^a_bgrad {x} \, dx = f(a)-f(b)$

Using this for the given line integral

$(x_2 +y_2-z_2) - (x_1 +y_1-z_1)$

= (1+2+0) - (0+1-(-1))

= 3-2
