Select the equation of the line graphed below:
y + 7 = 1(x + 6)
y – 7 = 1(x – 6)
y + 6 = 1(x + 7)
y – 6 = 1(x – 7)

Best ResponseYou've already chosen the best response.1select any 2 points that lie on the line for example  http://prntscr.com/8bp02w and then apply 2 point form which is  \[\frac{ yy _{1} }{ y_{2}y_{1} }=\frac{ xx_{1} }{ x_{2}x_{1} }\] where (x1,y2) and (x2,y2) are the cordinates of the 2 points :)

Best ResponseYou've already chosen the best response.1your line passes at point (7,6). For example if I substitute x=7 and y=6, into the secondequation, I get: \[\Large \begin{gathered} 6  7 = 1 \cdot \left( {7  6} \right) \hfill \\ \hfill \\  1 = 1 \hfill \\ \end{gathered} \] which is a false statement, so the second option can not be the right option. Please do the same with the other options

Best ResponseYou've already chosen the best response.1or u can do as @Michele_Laino said :) select any point the lies on the line an put its x and y cordinates in the options nd the one which satisfies is the answer :)

Best ResponseYou've already chosen the best response.1but sometimes it may happen that more than 1 equation satisfy the reason is that, that point may be the solution to those lines :) dw:1441188655630:dw

Best ResponseYou've already chosen the best response.1I think no, since if I substitute x=7 and y=6 into the third equation, I get: \[\Large \begin{gathered} 6 + 6 = 1 \cdot \left( {7 + 7} \right) \hfill \\ \hfill \\ 12 = 14 \hfill \\ \end{gathered} \] which, again, is a flase statement
