Use the system of equations and graphs below to complete the sentences

  Graph C; (2, 1)

Step-by-step explanation:

When equations are in standard form, finding the x- and y-intercepts is relatively easy. For ...

  ax +by = c

Using this idea on the first equation, we find its x-intercept to be -2. There is only one graph showing that has a line going through the point (-2, 0). That is Graph C. Checking the remaining intercepts for the two equations confirms that Graph C is the graph of this system of equations.

The two lines intersect at point (2, 1), so that is the solution to the system.
