Solve the problem. Write all linear equations in slope-intercept form. 15) Suppose that a sales person observes that if an item is priced at $8 per item then 11 items are sold. If 9 items are sold for $ 10 per item then find a linear equation to model the number y of items sold for x dollars per item. Find the slope-intercept form of the equation of the line. A) y =-x+3 B) y = x +3 C) y =-x + 19 D) y=x +19
