Solve the problem.A vendor has learned that, by pricing hot dogs at $1.00, sales will reach 120 hot dogs per day. Raising the price to $2.00 will cause the sales to fall to 68 hot dogs per day. Let y be the number of hot dogs the vendor sells at x dollars each. The linear equation y = -52x + 172 models the number of hot dogs sold per day when the price is x dollars each. Interpret the slope.
