She earns \$50 for each appliance that she sells plus a 5% commission on the price of the appliance. Write an equation that represents what she earned in a week in which she sold 15 appliances." I think the answer has to be something like slope-intercept form (y=mx+b) or point-slope form (y-y1=m(x-x1)). help, if not the answer, would be greatly appreciated. if an admin/mod reads this, please enable my drumthrasher account. idk what happened to it. __________________

an equation isn't a graph, I don't quite see there this is comming from...

anyway... yes the equation would be
amount earned = ((appliacnes price)*1.05) + 50) * 15

you can put x and y in there, but I don't see why you want to.
