The third one: y-1=56(x+8), in the pair -8, 1 the first number always is "x1" and the second number is always "y1".
So the formula is y-y1=slope(x-x1), you replace your pair and get the third option, you have solve the symbols of course for x

Find the surface area of the pyramid shown to the nearest whole number. The base is a regular hexagon.

Fiesta28 [93]

The surface area of the pyramid will be given as follows:
Area of triangles:
A=1/2×base×height
A=1/2×12×18
A=108 m²
Area of 6 triangles is given by:
A=108×6=648 m²

Area of the hexagon:
A=6×1/2×12×6√3
A=374.123m²

Total surface area:
SA=648+374.123
SA=1022.123 m²~1022 m²

Answer: C] 1022 m²
