You can put this solution on YOUR website!
Step 1: Isolate the y variable
x - 2y = 1
x - 1 = 2y
y+=+%281%2F2%29x-%281%2F2%29
...
comparing to y=mx+b, b is the y intercept
...
In this case -1%2F2 is the y intercept
Plot (0, -1%2F2)
...
For x intercept, set y = 0 and solve
0 = %281%2F2%29x-%281%2F2%29
%281%2F2%29+=+%281%2F2%29x
1 = x
Plot (1,0)
Draw a line through the intercepts.
