Best ResponseYou've already chosen the best response.2Point slope form \[\Large y  y_1 = m(xx_1)\] Make the proper substitutions to get \[\Large y  4 = 2(x3)\] now solve for y

Best ResponseYou've already chosen the best response.2now type in `solve(y4=2*(x3),y)` to have the TI89 solve for y. You'll have to do a slight rearrangement to get it into y = mx+b form

Best ResponseYou've already chosen the best response.2because you made x and y be defined based on those matrices we were working with earlier (which is my fault)

Best ResponseYou've already chosen the best response.2what you have to do is clear the RAM memory to free up x and y

Best ResponseYou've already chosen the best response.22nd key > 6 to bring up the MEM screen hit F1 and reset the RAM only (all RAM) do not touch the ROM at all because that's where the APPs are stored
