Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). her work is shown below. let (x2, y2) be (–7, 4) and (x1, y1) be (2, –3). m = = = the slope is . what error did she make? she simplified the denominator incorrectly. the denominator simplifies to –7. she labeled the points incorrectly. the point (–7, 4) should be (x1, y1). she used an incorrect formula. the formula should be the change in y-values with respect to the change in the x-values. she used an incorrect formula. the formula should be the sum of the x-values with respect to the sum of the y-values.

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
