7. (2,8.97)(4,11.95)     slope = (11.95 - 8.97) / (4 - 2) = 2.98/2 = 1.49 y = mx + b slope(m) = 1.49 (2,8.97)...x = 2 and y = 8.97 sub and fund b, the y int 8.97 = 1.49(2) + b 8.97 = 2.98 + b 8.97 - 2.98 = b 5.99 = b <== ur y int ==================== 8. (3,13.16)(5,15.94)     slope = (15.94 - 13.16) / (5 - 3) = 2.78/2 = 1.39   y = mx + b slope(m) = 1.39 (3,13.16)...x = 3 and y = 13.16 sub and find b, the y int 13.16 = 1.39(3) + b 13.16 = 4.17 + b 13.16 - 4.17 = b 8.99 = b <== ur y int
