Best ResponseYou've already chosen the best response.1The book gives me these answer choices and I'm totally not sure. y2=3(x15) y2=1/3(x+15) y15=3(x+2) y15=1/3(x+2) What does the x+ a number mean? :(

Best ResponseYou've already chosen the best response.1Oh.  15. I did +15.

Best ResponseYou've already chosen the best response.4Well a negative + negative makes the plus sign its just 15 not 15 so its just 3 same thing with the bottom it was 92 right? so i just added the 2 to get 11

Best ResponseYou've already chosen the best response.4Next step \[\huge yy_1=m(xx_1)\] where m=slope (x1,y1)

Best ResponseYou've already chosen the best response.1I understand how the formula goes. I just haven't used it in a few years. lol. But thank you for refreshing my memory. Anyways, I got y15=3/11(x2) and that's not a choice. :( Is there another step?

Best ResponseYou've already chosen the best response.4Like i said before the 2 is a negative 2 if two negative signs are next to each other they become postivie

Best ResponseYou've already chosen the best response.1Okay, what about the slope? It doesnt match up.. or maybe I just suck at math. lol.

Best ResponseYou've already chosen the best response.4Ok lets redo the slope hold on \[\LARGE \frac{1815}{92}=slope\] \[\LARGE \frac{1815}{9+2}=\frac{ 33 }{ 11 }\]

Best ResponseYou've already chosen the best response.4We can simplfy the slope (we made a mistake earlier 1815=33 not 3 )

Best ResponseYou've already chosen the best response.4So what would our final answer be? (which answer choice) ?
