Which graph best represents this system of equations and its solution?

`8x-4y=-16`

`3x+15y=-6`

Without the option of seeing the graphs provided, I can give a general overview of which graph would best represent this system of equations.

The first equation can be rearranged to:

`y = 2x + 4`

And the second equation can be rearranged to:

`y = -1/5x - 2/5`

From these rearranged equations, it can be seen that the lines will intersect at a single point, as the slopes and y-intercepts are different for each line.

Therefore, the graph that best represents this system of equations and its solution is one where the lines intersect at a single point. This would confirm that there is only one solution for the system of equations.
