To determine if (-2, 6) is a solution to the system of equations, we substitute the values of x and y into both equations and check if the equations are satisfied.

For the first equation:
x + 2y = 10
(-2) + 2(6) = 10
-2 + 12 = 10
10 = 10

For the second equation:
3x + y = 0
3(-2) + 6 = 0
-6 + 6 = 0
0 = 0

In both cases, the equations are true, so (-2, 6) is indeed a solution to the system of linear equations.

Based on the graph of the equations y=5x+10 and y=−2x+3, it appears that the two lines intersect at a point near (1, 15). Therefore, the estimate for the solution to the system of linear equations is (1, 15).
