Which graph best represents this system of equations and its solution?
8x-4y=-16
3x + 15y =-6
This system of equations can be simplified by dividing both equations by 4:
2x - y = -4
3x + 5y = -2
Graphing these equations will show two lines intersecting at the point (2, 0). Therefore, the graph that best represents this system of equations and its solution is the one with two lines intersecting at (2, 0).
