Anybody know the answer ??

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex

2x minus y equals 6, x plus y equals negative 3
