If two nonvertical lines are perpendicular, then the product of their slope is -1.An equivalent way of stating this relationship is to say that one line is perpendicular to another line if its slope is the negative reciprocal of the slope of the other. For example, if a line has slope 3, any line having slope - 1/3 is perpendicular to it. Similarly, if a line has slope - 4/5, any line having the slope 5/4 is perpendicular to it.

If you mean: y = -4x+3 then the perpendicular slope is 1/4

-(1/3)

x - 4y = 3 is the slope of a line perpendicular to line whose equation is y -5 3x plus 8 3.

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

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of a line that is perpendicular to a line with a slope of -2/3 is 3/2, (or 11/2 or 1.5).

-5/3 it is always the opposite reciprocal for a perpendicular slope

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

Slope of the given line is 3/7 So slope of perpendicular line is -7/3

3X + 5Y = 155Y = -3X + 15Y = (-3/5)X + 3The slope of this line is -3/5.The slope of a line perpendicular to it is 5/3.

Perpendicular line = - 1/gradient= - 1/2/3= - 3/2

Slope of given line = 3 So slope of perpendicular = -1/3

If we call the slope m we can say that the slope of the perpendicular line is -1/m In this case as the slope, m, is 13 the slope of the perpendicular is -1/13 or -0.07692307692

Perpendicular lines have slopes whose product is -1. As this is always true, if we think of .33 as about 1/3, then the perpendicular line would have a slope of -1/(1/3) which is -3.
