Standard form is ax+by=c normally a is positive and a and b are integres y=mx+b m=slope b=yint y=1/2x+3 minus 1/2 x both sides -1/2x+y=3 times -2 x-2y=-6
Well the answer would be $18.8784 but if you want it to be shorter it would be $18.88 because you multiply 17.48 and 0.08 and get 1.3984 and then you add it to $17.48
