I suppose you mean what is an opposite reciprocal? At any rate, we should start there. The opposite reciprocal is -(1/x) so let's take the number 5. The opposite reciprocal would be -1/5.

If you want two lines to be perpendicular you must take the original slope of the first line and change it to its opposite reciprocal.

For example: y=5x

A line perpendicular to this line would be y=-1/5x.

Do Perpendicular lines have opposite reciprocal slopes?

Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.


If one slope is -1 what is the slope of the perpendicular slope?

The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.


Slope of a line perpendicular to 2y equals -6x plus 8?

This question would be much easier if we simplified the equation first: 2y = -6x + 8 (divide both sides by two) y = -3x + 4 Now, the slope of this line is obviously -3. All you have to do to find the slope of a line perpendicular to the slope of another line is take its opposite reciprocal. "Opposite" means reverse the sign. "Reciprocal" means flip the fraction. In this case, the perpendicular slope of -3 (or -3/1) is 1/3. This is because 3 is the opposite of -3, and 1/3 is the reciprocal of 3.


How do you work out the gradient of a perpendicular line?

basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.


What is the slope of a perpendicular line if the slope of a line is -13?

A perpendicular lines slope is always the negative or opposite reciprocal of a lines slope. Therefore, if your slope is -13/1 then the perpendicularity of the other line is 1/13. The 13 would change positive there fore its its already a negative number then change it posiive.
