I am trying to get the answer for a problem It is: -2x +3x -5x - -8y +9

OpenStudy (anonymous):

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.
