To determine if the point (-2, 6) lies on the graphs of the equations x + 2y = 10 and 3x + y = 0, we can substitute the x and y values of the point into each equation and check if the equation is satisfied.
For the equation x + 2y = 10:
(-2) + 2(6) = 10
-2 + 12 = 10
10 = 10
The equation is satisfied for the first equation.
For the equation 3x + y = 0:
3(-2) + 6 = 0
-6 + 6 = 0
0 = 0
The equation is also satisfied for the second equation.
Therefore, the point (-2, 6) satisfies both equations and thus intersects both graphs.
