 Question 266165: when given 2 coordinates ie., (-3,-3) and (2,6) how do you know which one is y1,y2,x1,x2? which one would be put into the equation first as far as the top and bottom?Answer by checkley77(12569)   (Show Source): You can put this solution on YOUR website!(-3,-3) and (2,6) You can assign them either way: (x1,y1) and (x2,y2) [Slope=(y2-y1)/(x2-x1)] (6+3)/(2+3)=9/5 or: (x2,y2) and (x1,y1) (-3-6)/(-3-2)=-9/-5=9/5 Same answer.
