you are buying shingles for a roof. each bundle with cover 27 square feet. the roof consists of two rectangular parts and each is 70 feet by 30 feet. how many bundles of shingles do you need?

Ithink is a. true, but not sure

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
