Y+3x=6x+1 9x-3y=7. find the slopes and then state whether the lines are parallel or perpendicular.

Get the equations to have just one y.

y+3x-3x=6x+1-3x 9x-3y-9x=7-9x

y=3x+1 - 3y/-3 = (7-9x) / - 3

y=3x-3/7

If the slopes of each equation are the same, then the lines are parallel. These two lines are parallel.

Steps:

1. Solve the first equation

2. Subtract 3x on both sides

Y = 3x + 1

3. Your slope is 3

4. Solve second problem

5. Subtract 9x on both sides

-3y=-9x + 7

6. Divide everything by - 3

Y = 3x + 7/-3

7. Your slope is 3

8. Your answer is that they are parallel. Parallel lines have the same slope
