Four equations are graphed on the coordinate grid:

a coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. line a passes through the ordered pairs negative 8, 5 and 4, negative 7. line b passes through the ordered pairs negative 3, 8 and 2, negative 7. line c passes through the ordered pairs 0, 9 and negative 7, negative 5. line d passes through the ordered pairs 1, 4 and negative 4, negative 1 and is extrapolated further in the quadrant.

which set of equations has (−3, 0) as its solution?

a and b
b and d
b and c
a and d
