To find the solution for the system of equations, we can graph the two equations and find the point of intersection. Here's a graph of the given system of equations:
Graph:
The solution for the system of equations is the point of intersection between the two lines. From the graph, it appears that the lines intersect at the point (4, -3).
Therefore, the solution for the system of equations {y = -3x + 9, y = -x - 5} is x = 4 and y = -3.
