Answer:
y = -2x
Step-by-step explanation:
For direct variation: y = kx, where k is the constant of proportionality.
Given that Y equals -12 when x equals 6, we have -12 = k(6). Solve this for k by dividing both sides by 6:
k = -12/6 => k = -2
Then the "direct variation equation" here is y = -2x.

The volume of the pyramid is 
Explanation:
It is given that the base of the pyramid is a right triangle.
The formula to determine the volume of the pyramid is given by

where l is the base length of the pyramid,
w is the base width of the pyramid and
h is the height of the pyramid.
From the figure, we can see that,
,
and 
Substituting these values in the formula
, we have,

Multiplying the numerator, we get,

Dividing, we get,

Thus, the volume of the pyramid is
