The equations of two lines are x - 3y = 6 and y = 3x + 2. Determine if the lines are parallel, perpendicular or neither.

Question

anonymous · Answer

is it perpendicular

anonymous · Answer

The lines are perpendicular to each other. When you solve x-3y=6 you will get -3y=x+6 .... when you divide both sides by -3 ... you will get Y=-X/3 - 2.

The slope is flipped from the first. 

The slope of line 1 is Y=3/1x 

The second line is -X/3  ..... the slope is flipped.

When you flip the slope ... the slope becomes a perpendicular line.

Therefore, these lines are PERPENDICULAR to each other.

nope>>>> @rbeckford134  u have missed something... they r not perpendicular to each other
               x - 3y = 6
                3y = x -6
                  y = x/3 -2

so @rbeckford134  u r wrong :-(

@ISURU .... how are you getting positive 3? Its a -3y .....

The value X transfers across the = sign to become a -x  not a positive.

Remember that X stands place of 1 ... there for ... -X transfers over to become a -1.

Use the equation of a line .... Y = MX + B. @ISURU

When you graph the lines .... this is what you get:

hey ... watch the function of the line given in the question...
 it's
                 x - 3y = 6
