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.
