Answer:
A
Step-by-step explanation:
A . because the bottom of the pyramid is pentagon and so there will be 5 side surface ( five triangles)
The vector from the reference point on the line to the point is
.. (5-2, 1-3, 4-3) = (3, -2, 1)
The cross product of this with the line's direction vector (-1, 1, -3) is (5, 8, 1). The dot product of that with any of the points in the problem statement is 37. Your plane equation can be written as
.. 5x +8y +z = 37
_____
A suitable vector calculator is very handy for this. I used an HP-48 app on my phone.
Answer:
3/4x+2
Step-by-step explanation:
We can see the y intercept is 2 so our equation looks like this
y=mx+2
We just need to solve for m
We can take the point
(4,5)
and plug it in
5=4x+2
solve for x
x=3/4
