Is(-2,6) a solution to the system of these linear equations X plus 2Y equals 10 and 3X plus Y equals 0 why

No, because the graphs don’t intercept at (-2,6)
Yes, because the graph intercepts at (-2,6)
No because the graph intercepts at (-2,6)
Yes, because the graph don’t intercept that (-2,6)

No, because when you substitute X=-2 and Y=6 into the first equation X + 2Y = 10, you get -2 + 2(6) = 10 which simplifies to -2 + 12 = 10 or 10 = 10. This is not a true statement, so (-2,6) is not a solution to the system of linear equations.
