We know that the volume of a prism is defined by:

Substituting values:


This part of the plane is a triangle. Call it

. We can find the intercepts by setting two variables to 0 simultaneously; we'd find, for instance, that

means

, so that (4, 0, 0) is one vertex of the triangle. Similarly, we'd find that (0, 5, 0) and (0, 0, 20) are the other two vertices.
Next, we can parameterize the surface by

so that the surface element is

Then the area of

is given by the surface integral

Answer:
The slope of the line is
and a point on the line is
Step-by-step explanation:
The general point slope of line passing through
and having slope as m.

The given equation of the straight line,

Comparing this to the general equation we get the point as
and slope as
X2+7x-8=0
product=-8 times 1 = -8
sum= 7
{-1, 8}
x2-1x+8x-8=0
x(x-1)+8(x-1)=0
x+8=0 or X-1=0
x=-8
