Question 665921
Determine graphically the x-value when y=-6 in the given equation. 
-x+2y=-8

I got the answer x=-4. My assignment is asking for 2 lines, however. It is a multiple choice question. 

a.)One answer has one horizontal line across -6, and a line with the points and (2,-3)and intersecting with the horizontal line at (-4,-6) 
b.) Has a vertical line at -6 and another line at (0,4) with a intersection with the vertical at (-6,7)
c.) a horizontal line at-6 with another line intersecting with the horizontal line at (4,-6) and another point at -4,-2)
d.) a vertical line at -6 with another line intersecting with the horizontal line at (-6,7) and another point at (0,-4)

If I had to choose, I think the answer would be C or D. 
I hope I didn't make the question harder than it should be, with the choices. I just don't understand how to graph this. Thanks so much in advance for the help!


Why C or D? If you plug the coordinate points into the 2nd equation,: - x + 2y = - 8, will CHOICE C or D make the equation true? I doubt that very much!!!


Furthermore, y = - 6 represents a HORIZONTAL LINE, so that disqualifies CHOICE D for sure, since that choice has y = - 6 as being a VERTICAL LINE.


The answer is CHOICE {{{highlight_green(a)}}}
