Answer:
The solutions are the points (-3,0) and (-1,-2)
Step-by-step explanation:
we have
[tex]y=-x^{2} -5x-6[/tex] -----> equation A
[tex]x+y=-3[/tex] -----> equation B
Solve the system of equations by graphing
The solution of the system of equations are the intersection points both graphs
The solutions are the points (-3,0) and (-1,-2)
see the attached figure
