Horizontal lines have a slope of zero, and the slope of vertical lines is undefined.
Parallel lines have equal slopes, and perpendicular lines have slopes that are negative reciprocals of each other.
So we can say that:
Two nonvertical lines are parallel if and only if they have the same slope.
Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. That is, if the slopes are m1 and m2, then:
m1 = - 1/m2 or (m1)(m2) = -1

What is the slope of a line parallel to a line with slope -2?
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
Why are all horizontal lines parallel?
By definition, lines are parallel if they have the same gradient (slope). Any horizontal line has a gradient of 0, so it is parallel to any other horizontal line.
If two lines are parallel and one has a slope of 1.3 what is the slope of the other line?
If two lines are parallel and one has a slope of 1.3, what is the slope of the other line?
If two lines are perpendicular do the have the same slope?
No but if the two lines are parallel then they will have the same slope.
Lines with the same slope are?
Lines with the same slope but with different y intercepts are parallel.
What is the slope of a line parallel to a line with slope -2?
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
Why are all horizontal lines parallel?
By definition, lines are parallel if they have the same gradient (slope). Any horizontal line has a gradient of 0, so it is parallel to any other horizontal line.
What is the equation for parallel lines?
Parallel Lines have the same slope.
What types of slope do parallel lines have?
They don't, they are parallel to each other.
The two lines below are parallel If the slope of the red line is 3 what is the slope of the green line?
Parallel lines have the same slope.
Slope of parallel lines?
I don't exactly understand what you are trying to say in this question. However, one thing I can tell you about the slope of parallel lines is that they are equal. Parallel lines must have the same slope.
Do parallel lines have negative reciprocals?
The slope of parallel lines are the same, but the slope of perpendicular lines are negative reciprocals of each other.
If two lines are parallel and one has a slope of 1.3 what is the slope of the other line?
If two lines are parallel and one has a slope of 1.3, what is the slope of the other line?
Lines that have the same slope in math?
Lines that have the same slope are said to be parallel lines.
If one line has a slope of then the slope of a line parallel to it would be?
The same. Parallel lines have the same slope.
If is parallel to and the slope of is -5 what is the slope of?
The parallel lines will have the same slope of -5 but with different y intercepts
What is the slope of a line parallel to a line whose slope is 2?
2. Parallel lines have the same slope.
