Part a: 180 = 4m + b b = 180 + 4m 325 = 9m + b 325 - 180 = 9m - 4m 5m = 145 m = 29 b = 180 + 4(29) = 64 y = 29x + 64 part b: f(x) = 29x + 64 part c: at (4, 180) the points raise by 29, so day 5 (5, 209) day 6 (6, 238) day 7 (7, 267) day 8 (8, 296) day 9 (9, 325)

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
