Answer:
D. Rectangle
Step-by-step explanation:
If you cut the pyramid with a plane parallel to the base, a square is obtained. If the plane is perpendicular to the base, you can obtain two different figures; if the plane passes through the vertex, a triangle is obtained, but if it doesn't pass through the vertex, a trapezoid is obtained.
The point-slope form: 
m = 3; (-1; 5)
subtitute
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1)
m = 3; (-1; 5)
subtitute
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1)
