Find the arclength of the curve y = mx + b (m ≠ 0) from x = k l to x = k 2 (k l < k 2) using the arclength formula. Then verify your result using the Pythagorean theorem. Illustrate your work with a diagram. Homework Help ✎

If you were to create a slope triangle for the points (k1, k1m + b) and (k2, k2m + b), what would be the length of each leg of the slope triangle?
