Chapter 8.1, Problem 5E Step-by-step solution Step 1 of 2 5. (a) Any positively sloped straight line emanating from the point of origin will do. [See the broken line in Fig. 8.3b.] Step 2 of 2 (b) The equation for such a line is y = bx (with zero vertical intercept), so that dy/dx = b = y/x. Hence, by (8.6), the elasticity is 1, a constant.
