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

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?
