You can put this solution on YOUR website! This equation : 12x+2y=-48 is in standard form. Standard form is ax+by=c where the opposite of a divided by b (-a/b) is the slope and c divided by b(c/b) is the y-intercept. So in this case, we need -a/b. -a/b is -12/2 which equals -6. So your slope is -6. Hope this helped!
