The bottom left, lies never -6 on x axis and 20 on y axis
Answer:
9
Step-by-step explanation:
In the first octant, the given plane forms a triangle with vertices corresponding to the plane's intercepts along each axis.



Now that we know the vertices of the surface

, we can parameterize it by

where

and

. The surface element is

With respect to our parameterization, we have

, so the surface integral is
Answer: -2 and 4
Step-by-step: You see the horizontal line? now look at the the numbers -2 and 4 on that line. Notice how the line passes through them? those are your x-intercepts.
