Given the slope m = -0.6 and the point (19,17.6) from the graphPLUG IN to y = mx + b to find b, the y-intercept17.6 = -0.6(19) + b17.6 = -11.4 + bADD 11.4 to both sides29 = b
Therefore the EQUATION OF THE LINE is y = -0.6x + 29The height at 25 hours (that is, x = 25):PLUG IN x = 25 into above equation of the liney = -0.6(25) + 29y = -15 + 29y = 14Height of candle after 25 hours: 14 cm
