y=-1/4x+9/12
a. one
b. two
c. infinitely many***
d. none

One, they're both lines with a different coefficient so they'll only cross once.
That was a lie btw, they won't cross so d. their coefficient IS the same.
4x+16(-1/4x + 9/12) = 12
4x -4x + 12 = 12
0 = 0
they overlap
so C.

the lines are the same, infinite solutions.
