Question 614526: Using the graph, which of these ordered pairs is the best estimate of the solution of the system y = 3x + 2 and y = -1/4 x + 1?
A. (0.5, 0.5)
B. (-0.3, 1.1)
C. (1.2, 0.8)
D. (0.8, -0.5)
the points of these i found on the graph are
y = 3x + 2 (-2,-4) (-1,-1) (0,2)
y = -1/4 x + 1 (4,0) (0,1) (-4,2)

Hi, 

y = 3x + 2 (-2,-4) (-1,-1) (0,2)

 y = -1/4 x + 1 (4,0) (0,1) (-4,2)

Yes!  the idea is to plot the Pts and connect them with their respective Lines:

B. (-.3,1.1) looks to be the best estimate of where the Lines intersect (that PT is the solution for this system of equations.
