Answer:

Step-by-step explanation:
The given figure shows a triangular pyramid having 16 units as height. The base of pyramid is triangle.
The area of a triangular pyramid is given by :

Where
b is the area of base

So, the required area is equal to
.
ok so i can’t answer all of them BUT!! if a=a: infinitely many, x=a: one solution, a=k: zero solutions. hope this helps!
The slope is 2-2/6-6 which is zero . So the slope is no slope
X = 4 and Y = 9. I did a complicated way of doing it so if u copy it it would look weird
