For vertical lines, when you try to figure out the slope, you get zero in the denominator - in other words, a division by zero.

Why cant all linear equations be written in point slope form?

Not all linear equations can be directly expressed in point-slope form because this form requires a specific point on the line and the slope. However, some linear equations, like vertical lines, do not have a defined slope (infinite slope), making it impossible to represent them in point-slope form. Therefore, while most non-vertical linear equations can be converted to point-slope form, vertical lines present an exception.


Why is the 'X' co-ordinate written first in the co-ordinate of a point?

Because the x axis is horizontal and the y axis is vertical and they both are perpendicular to each other at the point of origin (0, 0)


Which of languages are written in top to bottom?

Languages traditionally written from top to bottom include Chinese, Japanese, and Korean, particularly in their vertical formats. In these languages, characters are arranged in vertical columns that are read from top to bottom and right to left. This style is often used in calligraphy and traditional literature. However, modern usage frequently includes horizontal writing as well.


What is two numbers written inside parenthesis separated by a comma?

Assuming you mean something like (5,7) this is often used for coordinates, in this case 5 along the X (or horizontal) axis and Y up the Y (or vertical) axis.


How do you graph y equals -1?

I'm pretty sure it's undefined meaning it is a vertical line. * * * * * No, it is not. It is a horizontal line, 1 unit above the x-axis. Its slope-intercept equation can be written as y = 0x + c : that is, slope = 0, intercept = 1.

Do equations have to be horizontal?

They do not HAVE to be, but the convention is to have them written horizontally. That makes it a little more universal.


What do you call the vertical bar in a fraction?

There is no vertical bar in a fraction. A fraction is written with either a horizontal bar or a slanted bar, which is technically called a "vinculum", but most people call it a "fraction bar".


How is a grid coordinate written?

A coordinate grid is squares. It has an origin where a vertical line, the y axis, and a horizontal line, the x axis, cross.

Which of the 50 states has a horizontal line of symmetry?

The states that have reflectional symmetry when written vertically in capital letters is Hawaii, Ohio, Iowa, and Utah. * * * * * A does not have horizontal symmetry - it has a vertical axis of symmetry. So only OHIO remains.


What direction was Sumerian cuneiform written?

Sumerian cuneiform was typically written from left to right in horizontal lines. However, it could also be written in vertical columns, going from top to bottom, or even in a combination of both directions.

How do you graph if there is no slope?

If there is no slope in a graph, it means that the line is horizontal. A horizontal line has a slope of zero. To graph a horizontal line, you simply draw a straight line that is parallel to the x-axis. The equation of a horizontal line is typically in the form y = k, where k is a constant value.


Where is the scale of a vertical bar graph written?
