Start with the given equation.
Subtract from both sides.
Rearrange the terms.
Divide both sides by to isolate y.
Break up the fraction.
Reduce.
So we can see that the equation has a slope and a y-intercept .
Now move onto the second equation.
Add to both sides.
Rearrange the terms.
Divide both sides by to isolate y.
Break up the fraction.
Reduce.
So we can see that the equation has a slope and a y-intercept .
So the slope of the first line is and the slope of the second line is .
Since the two slopes are neither equal nor negative reciprocals of one another, the two lines are neither parallel nor perpendicular.
