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).

∙ 13y agoAn equation where the slope is -3 has to have x being multiplied to -3. For example, you could have the equation y=-3x+2.

How do you know if two graphed lines are parallel or perpendicular?
if they are parallel they run side by side forever and will never cross. if they are perpendicular they will cross at a 90 degree angle. You can also tell just by looking at the equations for the lines if they are in the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept). When two lines are parallel, they have the same slope. When two lines are perpendicular, the slope of one is the negative reciprocal of the slope of other. For example, a line with a slope of 2 is perpendicular to a line with a slope of -½, and a line with a slope of 1 is perpendicular to a line with a slope of -1. (y = 1 and x = 1 are perpendicular because the slope of y = 1 is zero, the slope of x = 1 is infinity, the reciprocal of infinity is zero, and negative zero equals zero.)
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.
Find the equation of the line perpendicular when the slope is zero?
when the slope is 0, the graph is a horizontal line on the x axis so the y axis is perpendicular to it, which can be written x=0
Suppose the slope of AB is zero what is the slope of CD given that a. CD is parallel to AB b. CD is perpendicular to AB?
Any line that is parallel to another line will have the same slope. So if line AB's slope is zero and line CD is parallel to AB, then its slope will also be zero. The slope of line CD, when perpendicular to AB, will be infinity. If line AB has a slope of zero that means its just a horizontal line passing some point on the y-axis. A line that is perpendicualr to this one will pass through some point on the x-axis and therefore have an infinite slope.
What is the slope of all lines perpendicular to the line y equals 7?
All parallel lines have a zero slope.
What is the slope of a line perpendicular to a line whose slope is 3?
Slope of a line = m slope of perpendicular line = -1/m
What is the slope of a line that lies perpendicular to a line with a slope of 1 5?
The line perpendicular to a line with a slope of 1/5 has a slope of -5.
What is the slope of a line that is perpendicular to it?
The slope of a line perpendicular to one with a slope of m is -1/m.
What is the slope of a line that's perpendicular to a horizontal line?
A vertical line does not have a defined slope. If you think of slope as a fraction, it would be dividing by zero, which doesn't work. So, basically, no solution
What is a perpendicular line referring to slope in math?
The slope of a perpendicular line is not defined.
What is the slope of a perpendicular line is always?
The negative reciprocal of the slope of the line to which it is perpendicular.
Which formula is correct for the slopes of perpendicular lines?
if slope is given as m then perpendicular slope is -1/m (negative inverse)
