How do you know if two line segments are parallel?
Their slopes are equal.
How do you know if two line segments are perpendicular?
their slopes are negative reciprocals.
If two lines are parallel what do you know about their slopes?
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.)
If two lines are perpendicular what is the respective slopes equal to?
Given any line L, with slope m, the perpendicular line has slope -m.
What is the difference between slopes of parallel lines and slopes of perpendicular lines?
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 how or why not?
can a line have two slopes
Can one line have two slopes?
A straight line cannot have two slopes. A curve, however, might have a different slope at every different point.
Roof with two slopes and gable at both ends?
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.
How do you know if two line segments are parallel?
Their slopes are equal.
How do you know if two line segments are perpendicular?
their slopes are negative reciprocals.
If two lines are parallel what do you know about their slopes?
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.)
What type of slope does a line that slopes upward have?
A line that slopes to the right and up has a positive slope.
If there are two lines that are perpendicular and one of the two slopes is negative one third then what is the slope of the other line?
Positive 3
What line segments on a position versus time graph is physically impossible a horizontal line a straight line that slopes to the right a straight line that slopes to the left?
a verticla line
If two lines are perpendicular what is the respective slopes equal to?
Given any line L, with slope m, the perpendicular line has slope -m.
How do you know if two lines are intersecting lines with out graphing?
For two dimensional lines: Get the formulas for the two lines into a format so that you can evaluate the slope. If the slopes are different, then they will intersect. If the slopes are the same, then you have two parallel lines, or possibly, the two equations describe the same line.
What are the slopes of perpendicular lines called?
Slopes of line perpendicular to the x-axis are undefined.
