Question 119333: I need to graph this equation:
x+6=-5
it's supposed to be standard form like
Ax+By=C
My teacher said to use the numbers -2 -1 0 1 2 3
but they don't work.

If you subtract 6 from both sides, you get


That is the standard form with A=1, B=0, and C=-11.

So for any y value, x=-11.

Let's go ahead and solve this for x first:


Add -6 to both sides:



Now let's put that in standard form:



The A and C coefficients are easy, and . But there is no y term, so now what do we do? Another way to say there is no y term is to say there are zero ys in the equation, which means we can say that .

Hence, standard form would be:



Since none of the numbers in the set {-2,-1,0,1,2,3} make the equation true if you substitute them for x, substitute them for y instead. Since the coefficient on the y term is 0, you get the result no matter what value you choose for y.

Your table of values would then be:


Giving you a set of points to plot. You should end up with a vertical line that crosses the x-axis at, yep, you guessed it, (-11,0)

Hope that helps,
John
