The graph will cross at the coordinates (-2, 9)
<h3>How to solve equations?</h3>
y = 3x + 15
y = 3 - 3x
y = 3x + 15
Hence,
when x = 2
y = 3(2) + 15 = 21
when x = 0
y = 3(0) + 15 = 15
y = 3 - 3x
when x = 2
y = 3 - 3(2)
y = 3 - 6
y = -3
when x = 0
y = 3 - 3(0)
y = 3
Therefore, let's check if the equation will cross.
y = 3x + 15
y = 3 - 3x
using substitution,
3 - 3x = 3x + 15
3 - 15 = 3x + 3x
- 12 = 6x
x = -12 / 6
x = -2
y = 3 - 3(-2)
y = 3 + 6
y = 9
Therefore, the graph will cross at the coordinates (-2, 9)

Answer:
V = 211.56 mm
Step-by-step explanation:
The volume of a pyramid :
V = 1/3(Lenght * width * height)
Length = 9mm
Width = 8.2 mm
Height = 8.6 mm
Hence, we have ;
V = 1/3(9 * 8.2 * 8.6)
V = 1/3 * 634.68
V = 211.56 mm
