0 4

Line 2

0 7
1 5

Answer 1

a. 0
b. 1
c. 2
d. infinitely many

Answer 2

Why not plot these points, one table at a time, and draw a line thru them? Your graph should show you where the two lines intersect (if they intersect).

Answer 3

Each table will produce one graph.

Answer 4

hint parallel lines have the same slope and never meet
