# Thread: What did i do wrong

1. ## What did i do wrong

graph the liner equation x-y=1 I did it like this 4-y=1 y=3 the answer i got would be x=4 y=3. the answer in the book shows the line going through the bottom part of the graph not the top where my nswer would be. what did i do wrong ?

you need two point to draw the line, one you have I will use x=3, and x=1 for
my two points. The corresponding y's are y=2, and y=0.

So you line goes through (3,2) and (1,0). The attachment shows the line.
