To determine whether (-2, 6) is a solution to the system of equations, we need to substitute x = -2 and y = 6 into both equations and see if they hold true.
-
For the first equation: \[ x + 2y = 10 \] Substitute x = -2 and y = 6: \[ -2 + 2(6) = -2 + 12 = 10 \] This equation holds true.
-
For the second equation: \[ 3x + y = 0 \] Substitute x = -2 and y = 6: \[ 3(-2) + 6 = -6 + 6 = 0 \] This equation also holds true.
Since both equations are satisfied by the point (-2, 6), it is indeed a solution to the system of equations.
Thus, we can conclude that the correct statement is:
C. Yes, because the graphs don't intersect at (-2, 6).
It's important to note that "the graphs intersect at (-2, 6)" would be misleading in the context provided. The graphs intersect at that point, confirming it is a solution. However, the choice doesn’t reference that aspect properly as it implicitly states a false consequence. For clarity, the answer phrasing should ideally affirm that it is a solution without any misleading implications on intersection.
