Best ResponseYou've already chosen the best response.1ok... so the slope intercept form of a line is y = mx + b m is the slope and b is the y intercept simplifying the slope it becomes  1/3 so you have y = 1/3 x + b pick either point.... and substitute it into the equation to find b. if you choose (2, 3) substitute x = 2 and y = 3 into the equation and solve for b so 3 = 1/3 (2) + b can you do that..?

Best ResponseYou've already chosen the best response.1ok... so simplified the slope dw:1359753073245:dw so what do you think the equation is given the slope is 1/3 and b = 3 2/3

Best ResponseYou've already chosen the best response.1you said the slope is 2/6 which is the same as  1/3 take out the common factor of 2 so your equation is \[y = \frac{1}{3} x + 3 \frac{2}{3}\]
