Yes it can, but it would not then be a straight line but an angle.
Their slopes are equal.
their slopes are negative reciprocals.
If two lines are parallel, they have the same slope.(And if they are perpendicular, the product of their slopes is minus one - unless one line is horizontal and the other vertical.)
Given any line L, with slope m, the perpendicular line has slope -m.
Slopes of parallel lines have the same slope (they are changing at the same rate).Slopes of perpendicular lines have slopes that are the negative inverse of each other, that is, their product is -1. (The slope of a vertical line is therefore undetermined, not infinity. There is no slope s that times 0 equals -1.)---Let m1 be the slope of line one and m2 be the slope of line two. Then:If the lines are parallel, then their slopes are equal, so m1 - m2 = 0.If the lines are perpendicular, then their slopes are negative inverses of each other, so= m1 - (-1/m1)= m1 + 1/m1= (m12 + 1)/m1
can a line have two slopes
A straight line cannot have two slopes. A curve, however, might have a different slope at every different point.
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.
Their slopes are equal.
their slopes are negative reciprocals.
If two lines are parallel, they have the same slope.(And if they are perpendicular, the product of their slopes is minus one - unless one line is horizontal and the other vertical.)
A line that slopes to the right and up has a positive slope.
The slopes of two parallel lines are identical, meaning they have the same numerical value. This is because parallel lines maintain a constant distance from each other and do not intersect, which requires their slopes to be equal. If one line has a slope of ( m ), the other line will also have a slope of ( m ).
Two lines have slopes that are negative reciprocals if the product of their slopes equals -1. For example, if one line has a slope of 2, the negative reciprocal would be -1/2. This means that if one line rises 2 units for every 1 unit it runs, the other line falls 1 unit for every 2 units it runs, creating perpendicular lines.

Given any line L, with slope m, the perpendicular line has slope -m.
