What kind of lines have a slope of zero?
On the standard Cartesian graph, horizontal lines have zero slope. They all have the equation Y = a number
How many slopes do parallel lines have?
The lines all have the same slope.
How is it determined whether the lines passing through some specified points are parallel perpendicular or neither?
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
If a line has an undefined slope what can you say about the horizontal coordinates of each of the points on the line?
A vertical line has an undefined slope. If a line is vertical, the horizontal coordinate, commonly known as the x coordinates, must all be the same. If not, the line would not be vertical.
What is the slope of all lines perpendicular to the line y equals 7?
All parallel lines have a zero slope.
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 kind of lines have a slope of zero?
On the standard Cartesian graph, horizontal lines have zero slope. They all have the equation Y = a number
Do all lines have a slope?
Although all lines have the relationship that defines slope, one can argue that not all lines do have one. The exception would be vertical lines. Slope is defined as the vertical rate of change divided by the horizontal rate of change. In the case of a vertical line, there is no horizontal rate of change, and calculating slope would cause division by zero. The closest you could come to expressing the slope of a vertical line would be ∞
Do intersecting lines have the same slope?
Intersecting lines NEVER have the same slope. However, if the lines are identical, meaning all their points are the same, then they will, of course, have the same slope as well as everything else. On the other hand, parallel lines have the same slope, but they do not share a single point.
What is the slope of all lines parallel to the x-axis?
the x-axis is the horizontal line which means the slope is 0. any line parallel also has a slope of zero
How many slopes do parallel lines have?
The lines all have the same slope.
How is it determined whether the lines passing through some specified points are parallel perpendicular or neither?
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
What is the slope of horizontal line?
The slope of a horizontal line is zero. That's because the slope measures how steep the line is, and a flat line is not steep at all and therefore has no slope.
If a line has an undefined slope what can you say about the horizontal coordinates of each of the points on the line?
A vertical line has an undefined slope. If a line is vertical, the horizontal coordinate, commonly known as the x coordinates, must all be the same. If not, the line would not be vertical.
What is the slope of all lines perpendicular to the line y equals 7?
All parallel lines have a zero slope.
What is the imaginary horizontal lines that go the same way as the equator?
The set of imaginary lines that are all parallel to the equator are the parallels of latitude. Whether they're horizontal or not depends on how you hold your map.
What are all horizontal lines parallel to?
other horizontal lines? which would be 180 degrees i guess.
