That is an expression. Are you supposed to simplify it?
OpenStudy (anonymous):
Are you grouping? There is no "answer."
OpenStudy (anonymous):
-4x+8y+9 is the solution by grouping
OpenStudy (anonymous):
if you equate this expression to some other expression involving x, y and constants you would get something like Ax+By+C=0 which is the equation of a straight line.
