Answer:
the horizontal line through y = 1.5
Step-by-step explanation:
The equation ax + by = c becomes 0x + 1y = 1.5 when a = 0, b = 1 and c = 1.5 are substituted.
0x + 1y = 1.5 becomes y = 1.5.
The graph of this equation is the horizontal line through y = 1.5.
There are 4320 choices.
By the fundamental counting principle, we take choices x choices x ...
This means we take 10(4)(12)(9)=4320
