For this case, the first thing to do is to observe the cut points with the y axis and the x axis. We have then that for the following equation: y = -3x + 15 The cut points are: Axis x: 0 = -3x + 15 3x = 15 x = 15 Axis y: y = -3 (0) +15 y = 0 + 15 y = 15 Therefore, the line that best approximates the data is: y = -3x + 15 Answer: y = -3x + 15
