What if the slope is negative already what would be the reciprocal?

It would be the negative of the negative reciprocal. And since the negative of a negative is a posivie, it is the positive reciprocal.. For example, if the slope was -3, the other would be 1/3.

What is the negative reciprocal of a slope?
The negative reciprocal of any gradient gives the gradient of the line perpendicular to it. If you had a line of gradient 2, the negative reciprocal would be -1/2 Just change the sign on the number and flip the number/fraction to get the negative reciprocal.
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.
What is the negative reciprocal of 0?
The negative reciprocal of zero would be any undefined fraction. 0/x=0 negative reciprocal: -(x/0)= undefined.
What is the negative reciprocal of -3?
The reciprocal of a number is 1 divide by that number - the reciprocal of -3 is 1/(-3), or -1/3. So, the negative reciprocal of -3 would be 1/3 (without the minus sign).
What is the slope of a line perpendicular to x - 3y 9?
x - 3y = 9 can be rewritten in y = mx + b notation as y = x/3 - 3. The slope of this line (m) is 1/3. To find the slope of a perpindicular line, multiply m by negative one and take the reciprocal. So the slope of the new perpindicular line would be -3.
What is the negative reciprocal of a slope?
The negative reciprocal of any gradient gives the gradient of the line perpendicular to it. If you had a line of gradient 2, the negative reciprocal would be -1/2 Just change the sign on the number and flip the number/fraction to get the negative reciprocal.
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.
What is the slope of a line that is perpendicular?
If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.
What is the definition of a negative reciprocal?
Negative reciprocal is something you use in math that often times help you find a perpendicular line to an equation. ex: for an equation with a slope of 5x, the recriprocal would be -1/5x. what you do is you flip flop the bottom and the top, 1/5x. That is the reciprocal alone and to make it a negative reciprocal you just simply add the negative sign.
What is the negative reciprocal of 0?
The negative reciprocal of zero would be any undefined fraction. 0/x=0 negative reciprocal: -(x/0)= undefined.
What is the reciprocal of negative 17 over 3?
the reciprocal would be negative 3 over 7, unless you are trying to find the negative reciprocal, then the answer would be positive 3 over 7. hope this helped you :)
What is the slope of a line perpendicular to line -2x 9y-8?
Without an equality sign and not knowing the plus or minus value of 9y it can't be considered to be a straight line equation. But in general the perpendicular slope is the reciprocal of the slope of the equation. As for example if the slope was 3 then its reciprocal is -1/3. And if its slope was -3 then its reciprocal would be +1/3
How do you write an equation that is purpendicular to another?
Make the slope a negative reciprocal. That means that you change the sign ( a positive number becomes negative or a negative number becomes a positive ). You also flip the slope as though it were a fraction (4/5 becomes 5/4. And 2/1 becomes 1/2). So if the slope was 3x it would now be -1/3x.
What is the negative reciprocal of -3?
The reciprocal of a number is 1 divide by that number - the reciprocal of -3 is 1/(-3), or -1/3. So, the negative reciprocal of -3 would be 1/3 (without the minus sign).
Are two lines with different slopes perpendicular?
Only by coincidence. Two lines on a graph are perpendicular if and only if one slope is the negative reciprocal of the other: meaning that if one line has a slope of 3/2, the other would have to have a gradient of -2/3.
What would a graph that has a negative slope show?
It would have a downhill slope from left to right
