Best ResponseYou've already chosen the best response.0If A is at \((x_{A}, y_{A})\) and B is at \((x_{B}, y_{B})\), then slope is \(\large \frac{y_{B}  y_{A}}{x_{B}  x_{A}}\)

Best ResponseYou've already chosen the best response.0Ok so what do I do once I have the slope?

Best ResponseYou've already chosen the best response.0Then you use it to find the yintercept. Remember, the yintercept is at point \((0, y_{C})\)

Best ResponseYou've already chosen the best response.0So, if you used point A, you could use \(\large m = \frac{y_{C}  y_{A}}{0  x_{A}}\)

Best ResponseYou've already chosen the best response.0Then put it in the form y = mx + b. m is the slope, and b is the yintercept.

Best ResponseYou've already chosen the best response.0Ok,I understand that part but how do i find teh standard form of the equation,my book says it would be Ax +By=C but it doesn texplain how to find the equation using 2 given points.

Best ResponseYou've already chosen the best response.0Oh, sorry. I missed that part of your post. Standard form is just \(Ax + By = C\) (like you said). You can get it by rearranging your y = mx + b formula.

Best ResponseYou've already chosen the best response.0Bring y and mx to the same side, to equal b.

Best ResponseYou've already chosen the best response.0Ok so I have teh x and y intercepts figured out but how do I find C?

Best ResponseYou've already chosen the best response.0C is just b (from y = mx + b)
