Best ResponseYou've already chosen the best response.1There are a few ways of finding the slope: 1. Directly (using slope formula) 2. Graphically (using rise/run) 3. Algebraically (using y = mx + b)

Best ResponseYou've already chosen the best response.1If you want to find it algebraically, you have to insert each point, one at a time, into the equation y = mx + b. Doing that, you'll get 1 = 2m + b 3 = 6m + b

Best ResponseYou've already chosen the best response.1Okay, then use this slope formula: \[m = \frac{y_2  y_1}{x_2  x_1}\]

Best ResponseYou've already chosen the best response.1slope = (3  (1))/(6  2) slope = (3 + 1)/4 slope = 4/4 slope = 1
