What does a straight vertical line on a graph mean?
A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane. All points on the line will have the same x-coordinate. In the figure above, drag either point and note that the line is vertical when they both have the same x-coordinate. A vertical line has no slope.
What is the equation for a straight vertical line?
The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept . (link) For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2.
What is a vertical line on a graph called?
The vertical line in the given graph is called Y-axis. In the Cartesian coordinate system, the vertical reference line is called Y-axis.
What is the slope of a straight vertical line?
Vertical lines have an undefined slope because the horizontal change is 0 — you cannot divide a number by 0.
What does vertical line mean?
Definition of vertical line : a line perpendicular to a surface or to another line considered as a base: such as. a : a line perpendicular to the horizon. b : a line parallel to the sides of a page or sheet as distinguished from a horizontal line.
What is a vertical line in math?
A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right.
What is the vertical axis on a graph called?
The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.
What is a straight line on a graph called slope?
all have graphs which are straight lines. The slope and intercept of a straight line. In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. Lines with a positive gradient slope upwards, from left to right.
How do you find the slope of a straight line on a graph?
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
What’s the slope of a straight vertical line?
undefined slope
Zero slope means that the line is horizontal: it neither rises nor falls as we move from left to right. Vertical lines are said to have “undefined slope,” as their slope appears to be some infinitely large, undefined value.
What is the slope of a straight line on a graph?
The slope of a vertical line is undefined. That’s because, in a horizontal line, the change in the x-value will always be 0.
Is a straight line on a graph undefined?
A line has an undefined slope when it is a vertical line. A vertical line has no horizontal distance to it which is needed to have a positive, negative, or zero slope. An example of the equation of a line with an undefined slope would be x=4 .
