Question

The graph plots four equations, A, B, C, and D:

Answer 1

For this case, the first thing you should do is observe the intersession of the lines.
 The solution of the intersection of the lines will be given by an ordered pair of the form:
 (x, y)
 So, for the next ordered pair:
 (x, y) = (0, 8)
 We have the lines that intersect are:
 Line A
 Line C
 Answer:
 A pair of equations that has (0, 8) as its solution are:
 Equation A and Equation C

Answer 2

By looking at the graph, it seems Equation A and Equation C both intersect at (0, 8). So the first answer is correct.
