I NEED HELP ASAP Luke usually goes to the store and buys a certain brand of cereal that costs $3.50 per box. Luke changes to shipping the order to his house instead of going to the store, the only issue is that he also pays $3.00 for shipping. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.

y = 2.90x + 3.00

Part A: How much more is the price of a box of Luke's original brand of cereal than the price of a box of the super-saving brand? Show your work. (2 points)

Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work. (3 points)

Ted and meg have each drawn a line on the scatter plot shown below: the graph shows numbers from 0 to 10 on x and y axes at increments of 1. dots are made at the ordered pairs 1, 8 and 2, 7.5 and 3, 6 and 4, 5.5 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 1.9 and 9, 1.2 and 10, 0. a straight line labeled line p joins the ordered pairs 0, 8.5 and 10.1, 0. a straight line labeled line r joins the ordered pairs 0, 8.5 and 7.8, 0. which line best represents the line of best fit? line p, because it is closest to most data points line p, because it shows a positive association line r, because it is closest to most data points line r, because it shows a negative association
