Question 1147065
<font face="Times New Roman" size="+2">


I have no idea how <b><i>you</i></b> would do it.


You could select a series of values for the *[tex \Large x] variable and solve the equation for *[tex \Large y] for each chosen *[tex \Large x] value, giving you a set of ordered pairs (since both of the variables are linear, i.e. nothing raised to a power higher than 1, you only need two ordered pairs, but a third or fourth one is good for checking your arithmetic).  Plot your ordered pairs and draw a straight line through them.


Or you could find a graphing calculator or program and enter the relation to see what you get.


Or you could do what I did when I first looked at your problem.  I added *[tex \Large x] to both sides of the equation and recognized the equation of a line in slope-intercept form with a slope of 1 and a *[tex \Large y]-intercept of *[tex \Large (0,\,-1)] and then sketched this:

My calculator said it, I believe it, that settles it
