info@snapandsolve.comThe empty suitcase weighs 9 pounds. This is determined from the graph where the line intersects the y-axis at (0, 9).
The equation for w, the weight of the suitcase, with b books in it is: w = 3.8b + 9. This is derived from the slope of the line, which is 3.8 (from the points (0, 9) and (6, 31.8)), and the y-intercept, which is 9.
