First find the slope/rate of change of the table. Find the difference between the intervals of the x and y values of the table. Each time the x value decreases by 2 the y value decreases by 4. To find the rate of change divide the -4 by -2 to get 2 as the slope.

Set up an equation using values from the table to figure out the y intercept or b value.
-6=-4(2)+b
-6=-8+b. Add 8 from both sides
both sides to get b
2=b
The y intercept is (0,2)

The equation of the line is Y=2x+2

Plug in 0 for y into the lines equation to get the x intercept

0=2x+2
-2=2x. Divide by 2 to isolate x
-1=x

The x intercept is (-1,0)

Using cylindrical coordinates,

$\displaystyle\int_{x=0}^{x=\sqrt3}\int_{y=0}^{y=\sqrt{3-x^2}}\int_{z=5+2x^2+2y^2}^{z=11}\mathrm dz\,\mathrm dy\,\mathrm dx$
$\displaystyle=\int_{\theta=0}^{\theta=\pi/2}\int_{r=0}^{r=\sqrt3}\int_{z=5+2r^2}^{z=11}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$
$=\displaystyle\frac\pi2\int_{r=0}^{r=\sqrt3}r(11-(5+2r^2))\,\mathrm dr$
$=\displaystyle\pi\int_{r=0}^{r=\sqrt3}(3r-r^3)\,\mathrm dr$
$=\dfrac{9\pi}4$
