Okay,. So i have this project due on monday,. and we have to make a story of 2 people who travel on on a boat to another place,. but at one point they will have to meet (their boats will have to cross eachothers paths) in the ocean,.

i already have my coordinates and everything,. but it is asking me to find the slope and the y-intercept because we will also have to graph it,.

i dont really have a problem with the graphing part but i don know how to find the slope or the y-intercept,. it has always been really hard for me.

okay so my coordinates are

(40N, 74W) to (29S, 24E) [new york to cape town south africa

(0N, 49W) to (41N, 2E) [amazon r. to barcelona spain)

how would i find the slope and the y-intercept

and then with that i need the linear equation for the route.

but since i dont really know if some will be negative or positive,. i dont know if North, West, South, or East whichones are positive and negative??

please help!?
