Question

Find the area of the surface given by 
? = ?(?, ?) that lies above the region ?

The given text describes a function and a region of interest in the Cartesian plane.

**Function:**
\[ f(x, y) = -3x - 2y + 6 \]

This is a linear function of two variables, \(x\) and \(y\).

**Region:**
\[ R = \{(x, y) : 0 \leq x \leq 2, 0 \leq y \leq 2 - x \} \]

This region \(R\) is defined by the constraints:
- \(x\) is between 0 and 2, inclusive.
- \(y\) is between 0 and \(2 - x\), which forms a line with a negative slope.

The set \(R\) describes a triangular region in the first quadrant of the coordinate plane, bounded by the line \(y = 2-x\), the \(x\)-axis, and the vertical line \(x = 2\).
