Question 1033674: Using the graph for reference, what do you estimate the solutions are to this quadratic system?
Graph: http://postimg.org/image/4hnymqhe9/
Choices:
(5, 0)
No solution
(�-5, 0), (�-3, 0) and (1, 0)
(�-3, �-8)

Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
i would say (-3,-8).
that's the intersection of what looks like a vertical line with the graph of the quadratic equation.
if it's a system of equations, you are looking for the common solution.
on the graph, the common solution is the intersection of the two graphs.
looks like the parabola is the graph of one equation and what looks like a vertical line is the graph of the other equation.
their intersection would be the solution.
this looks like it is a linear-quadratic system.
that's where one of the equations is a straight line and the other equation is a parabola.
the key word was system, which indicates a system of equations.
that's what i understand.
the intersections of the graphs with the x-axis would not apply as far as i can tell.
if you were looking for a solution to the quadratic equation, then you would look for the intersection of the parabola with the x-axis.
as far as the vertical line is concerned, i don't believe it's intersection with the x-axis would be called a solution.
