Best ResponseYou've already chosen the best response.0take either coordinate set, doesnt matter; and plug it into: y = (3/8)x + b and solve for (b) Lets use (2,1)... 1 = (3/8)(2) + b 1 = (6/8) + b 1 + (6/8) = b (8/8) + (6/8) = b (14/8) = b we can reduce (14/8) to (7/4) since we know (m) and (b); lets get rid of the values for (x) and (y) to form the equation: y = (3/8)x + (7/4)

Best ResponseYou've already chosen the best response.0yeah; i missed something... (3/8)(2) is not a negative, its a positive 1 = (6/8) + b 1  (6/8) = b (8/8)  (6/8) = b (2/8) = b 2/8 reduces to 1/4 itll get ya everytime :)
