Answer: Choice A) 3x+4y = 12

---------------------------------------------------------------------

y = (-3/4)x + 3
4*y = 4*((-3/4)x+3) ... multiply both sides by 4 to clear out the fraction
4y = -3x+12 ... distribute and multiply
4y+3x = -3x+12+3x ... add 3x to both sides
3x+4y = 12

Note: this is in standard form Ax+By = C where A = 3, B = 4 and C = 12.
