First, all of these numbers are even, so halving everything would be a nice place to start:2x-y=1

Then, rearrange to get y on one side of the equation:

2x-y=1

-y=1-2x

y=-(1-2x)

y=2x-1

Finally, check the coefficient of x (number being multiplied by x):

y=2x-1

Therefore the slope of this line is 2.
