a = slope of the linear graph (constant value) = b = vertical intercept of the linear graph (the value of y when x is 0) Hence, we can represent the above equation using a linear graph as follows. slope = a = Now, let us compare different graphs. 2.1 Different intercepts but same slope. 2.2 Upward sloping vs. downward sloping ................
