Question 130686
The domain is the x value. The range is the y value.  Alphabeticly domain comes before range.   Alphabaticly, x comes before y.   Therefore x=domain and y= range.

x-2y=1
x=2y+1   Solve equation for x.
x=2(-2) +1
x=-4+1=-3    Substitute the first value in the range for y and solve for x.
             Continue this process for each number in the range.
x=2(0)+1
x=1

x=2(5)+1
x=11

x=2(8)=1
x=17
Domain is -3,1,11,17
