Any line that has an undefined slope is a vertical line, that has no y-intercept. Therefore the equation of a line with an undefined slope is x = a, where a = x-intercept. Here a = 1. Thus the required equation is x = 1. Answer: The equation of a line with an undefined slope passing through (1,2) is x = 1

The slope of a vertical line is undefined because the x-coordinates are the same. The denominator becomes zero in the calculation of slope as there is no change in x-coordinates. What is the x-Intercept of a Vertical Line? If the equation of a vertical line is x = a, then its x-intercept is (a, 0). Does a Vertical Line Have a Slope? A vertical ...
Therefore, the slope formula will always result in division by zero and therefore the slope will be undefined. Summary. We have seen how the slope of a line may be undefined. The other possibilities when calculating the slope are: Negative slope – the line falls from left to right. Positive slope – the line rises from left to right. Zero ...

In math, vertical lines are typically found in a coordinate plane, though they can also be found in geometric shapes as lines of symmetry, as well as in other areas of math. In a coordinate plane, a vertical line is defined as a line that is parallel to the y-axis. The y-axis itself is a vertical line, so it follows that any line parallel to it is ...
The slopefor a vertical line is undefined. This is because there is no change in x-value, so if we plug values into the slope equation, we will end up with a 0 in the denominator. As an example, using the points (-4, 0) and (-4, 3) for the vertical line below, the slope is, which is undefined since we can't divide by zero. The graph below shows the...
The equation of a vertical line is, This is derived from the standard form for the equation of a line, Ax + By = C, where A = 1, B = 0, and C = b: where b is the x-intercept. In other words, the coordinate of the x-intercept defines the equation of a vertical line.
Below are some properties of vertical lines: 1. Every vertical line intersects the x-axis. 2. Every vertical line is parallel to the y-axis. 3. Vertical lines have undefined (or infinite) slope. 4. Vertical lines have no y-intercept; they are parallel to the y-axis so they do not intersect.
The vertical line test is used to determine whether a given graph is a function: 1. If a vertical line can be drawn such that it intersects a given graph at only one point, the graph is a function. 2. If a vertical line cannot be drawn such that it intersects a given graph at only one point, the graph is not a function. As an example, a circle is n...
Vertical lines and horizontal lines are counterparts. Vertical lines travel up and down while horizontal lines travel left to right. The table below shows some of the differences between horizontal and vertical lines:
Let's use two points from the line x=0 and calculate slope. (0,1),(0,−3) m=−3−10−0m=−40. This gives us a fraction with a 0 in the denominator. We cannot divide by zero, so our slope is undefined. The picture above shows how every vertical line, no matter where it is on the x-axis, has an undefined slope.
Oct 6, 2022 · But we can’t divide by 0. Division by 0 is not defined. So we say that the slope of the vertical line x=3x=3 is undefined. The slope of any vertical line is undefined. When the x-coordinates of a line are all the same, the run is 0.
