There is one critical point at (2, 4), but this point happens to fall on one of the boundaries of the region. We'll get to that point in a moment.
Along the boundary  , we have
, we have

which attains a maximum value of

Along  , we have
, we have

which attains a maximum of

Along  , we have
, we have

which attains a maximum of

So over the given region, the absolute maximum of  is 1578 at (2, 44).
 is 1578 at (2, 44).

Answer:
A. 
Step-by-step explanation:
We are given the two points (2,7) and (4,-1).  In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:

Thus, the slope is -4. 
Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is: 

Where (x1, y1) is a coordinate pair and m is the slope. 
Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively: 

This is also slope-intercept form. The answer is A.
