9.
Which system has a solution in which the y value is negative?

y = -2/3 x and y = 3x - 3


y = 3x + 2 and y = -1/4 x + 1


y = -1/4 x + 1 and y = -2/3 x


y = 3x + 2 and y = -2/3 x


10.
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?

(0.5, 0.5)


(-0.3, 1.1)


(1.2, 0.8)


(0.8, -0.5)
