Best ResponseYou've already chosen the best response.1We have three points: (10,27), (11,m), (12,11) Let's pick two of them, say (10,27) & (11,m)

Best ResponseYou've already chosen the best response.1You plug those coordinates into the slope formula \[\Large Slope = \frac{y_{2}y_{1}}{x_{2}x_{1}}\] \[\Large Slope = \frac{m27}{1110}\] replace "slope" with 8 because this is what we want the slope to be \[\Large 8 = \frac{m27}{1110}\] from here you solve for m
