1. Match each graph with its description.
A card sort is on the screen. To start dragging a card, Tab to it and press M to mark it. Next, Tab to the card where you want to drop, and press J to join the two cards together. To unjoin the selected card from a group, press U.
No solution
One solution: (1,3)
One solution: (−8,1)
Infinitely many solutions
The graph with no solution would be graph A.
The graph with one solution of (1,3) would be graph D.
The graph with one solution of (-8,1) would be graph C.
The graph with infinitely many solutions would be graph B.
