To illustrate the steepness and direction conveyed by the slope,

(a) draw five separate lines each with y intercept (0, 0) and having slopes of 1/4,1/2, 1,2, and 4 respectively;

(b) draw five separate lines each with y intercept (0, 4) and having slopes of −4, −2, −1, -2/3 and - 1/2, respectively.

(a) See Fig. 2-12(a);

(b) see Fig. 2-12(6).
