The number of miles that can be driven is proportional to the number gallons of gas. The graph of the equation y = 31x shows this relationship. Explain why the ordered pair (0, 0) is on this graph.
A. When the tank is full, 0 miles can be driven.
B. When 0 miles are driven, there is no gas used.
C. When there is no gas in the tank, 0 miles can be driven.
D. When the tank is full, the driver does not have to worry about how much gas is used.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
