estimate the solution to the system of these linear equations based on the graph.

y = 2x + 3
y = 1/2x + 6
a (-2, 7)
b (7, 2)
c (2, 7)
d (2, -7)

Based on the graph of the two equations, it seems that the solution to the system of equations is point A (-2, 7). This is where the two lines intersect, and it is the only point that lies on both lines.
