One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.

Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.

No. They are parallel.

The slope of the perpendicular is -(1/2) .

No, the two lines are not perpendicular.

10 is.

They are both parallel because the slope or gradient is the same but the y intercept is different.

Slope of given line = -3 Therefore, slope of perpendicular = 1/3

It is: minus 1.25

The slope of both lines is 8. So they're parallel.

They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.

[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.

For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )

-5/3

- 1/3

It is -1/2

The equation of such a line is [ Y = -4x plus any number].

No - but it is a straight line graph !
