Perpendicular lines do not have the same slope. The slopes of perpendicular lines are different from one another in a specific way. The slope of one line is the negative reciprocal of the slope of the other line. The product of a number and its reciprocal is 1.
Do perpendicular lines have the same Y intercept?
They are not the same line. ... The slopes of the lines are the same and they have different y-intercepts, so they are not the same line and they are parallel. Perpendicular Lines. Two non-vertical lines are perpendicular if the slope of one is the negative reciprocal of the slope of the other.
Do perpendicular lines have opposite slopes?
Explanation: Perpendicular lines have slopes that are the opposite of the reciprocal of each other. In this case, the slope of the first line is -2. The reciprocal of -2 is -1/2, so the opposite of the reciprocal is therefore 1/2.
