Asystem of linear equations is graphed.

which ordered pair is the best estimate for the solution to the system?

a) (, 1)
b) (, 0)
c) (1,1)
d) (, 0)

(this graph was also provided in the question)

The solution of a system, in graphic terms, is where the lines intersect. Ordered pairs follow this form (x,y). Note that all x values are on the horizontal line (think of running when you think of x) and all y values are on the vertical line (think of jumping when you think of y).

According to the graph, y is 0 since the inserect is directly on the x-axis. So (-,0). Cross out A and C because these answer choices do not have '0' as their y-value. This leaves (1/2,0) or (1/3,0). The answer that seems most likely is D. 0.5 (1/2) is closer to 1, and can rounded to 1, opposed to  0.3 (rounded 1/3) The point of solution seems close to one.
