In two-dimensional geometry, there room two axes, which space the x-axis and the y-axis. A line that is parallel come the y-axis is of the form "x=k", where "k" is any real number and also "k" is the distance of the line from the y-axis. For example, the equation that a line which is the the form x = 3 is a line parallel come the y-axis and is 3 devices away from the y-axis. Similarly, lines deserve to be attracted parallel to the x-axis also. A line that is parallel to the x-axis is the the form "y=k", where "k" is a genuine number and is likewise the distance of the heat from the x-axis. For example, the equation of a heat which is that the type y = 2 is a line that is parallel come the x-axis and is 2 devices away indigenous the x-axis.

## Line Parallel to x-axis

A line the is parallel come the x-axis is of the type "y = k", whereby "k" is a continuous value. In a coordinate plane, a directly line can be represented by one equation. To placed the equation of this parallel heat in a an ext generalized form, we deserve to write it as "y = k", where "k" is any real number. Also, "k" is stated to be the distance from the x-axis to the heat "y=k". For example, if the equation that a heat is y = 5, climate we deserve to say the it is in ~ a street of 5 units over the x-axis line. All the clues on a line that is parallel come the x-axis room at the very same distance away from it.

Consider the equation y = 2, or y - 2 = 0. This is an equation v a solitary variable *y*. However, we can think that it together a two-variable straight equation in which the coefficient the *x* is 0:

0(x) + 1(y) + (-2) = 0.

Let united state plot the graph because that the equation, and find just how the line "y=2" will look.

x | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 |

y | 2 | 2 | 2 | 2 | 2 | 2 | 2 | 2 | 2 |

Substituting every value of "x" provided in the table, we check out that the worth of "y" stays unchanged. For example, let us take the worth of "x = -4" and also substitute in the equation, 0(x) + 1(y) + (-2) = 0. 0(-4) + 1(y) - 2 = 00 + y - 2 = 0Therefore, y = 2.Let us take a hopeful value because that "x = 3" and solve the equation to discover the worth of "y". 0(3) + 1 (y) - 2 = 00 + y - 2 = 0y = 2.Therefore, we deserve to see the though the worth of "x" changes, the value of "y" continues to be unchanged. Thus, all services of this direct equation are of the form (k,2), whereby *k* is some genuine number. The graph the the line "y=2" is given below.

This is a heat parallel come the *x*-axis. Thus, one equation of the form y = a represents a right line parallel come the *x*-axis and also intersecting the *y*-axis in ~ (0,a).

## Line Parallel to y-axis

A line that is parallel come the y-axis is x = k, wherein "k" is a continuous value. This means that for any type of value that "y", the value of "x" is the same. A more generalized way to represent an equation of a right line parallel to the y-axis is x = k, wherein "k" is a actual number. Here, "k" to represent the street from the y-axis come the heat "x=k". For example, if we have actually the equation that a line together "x =2", it claims that the heat is in ~ a street of 2 systems away indigenous the y-axis. All the clues on a line the is parallel to the y-axis space at the same distance far from it.

Now, take into consideration the equation x = 3. This can additionally be composed as a two-variable straight equation, together follows:

1(x) + 0(y) + (-3) = 0.

Let us plot the graph for the equation, and find just how the line "x=3" will look.

x | 3 | 3 | 3 | 3 | 3 | 3 | 3 | 3 | 3 |

y | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 |

Substituting various values the "y" in the equation, 1(x) + 0(y) + (-3) = 0, the worth of "x" continues to be unchanged. For example, if y = -3, climate the value of "x" is,1(x) + 0(-3) +(-3) = 0.x + 0 - 3 = 0x -3 = 0Therefore, x = 3.Let us take a confident value because that "y". Say "y=2". ~ above substituting the worth of "y=2", us get,1(x) + 0(2) + (-3) = 0x + 0 -3 =0Therefore, x = 3. We can observe the for any type of value of "y", the worth of x = 3. Thus, the options of this equation are all of the form (3,k), whereby *k* is some genuine number. The graph of this equation will consist of every points who *x*-coordinate is 3, the is, a heat parallel come the *y*-axis, and passing through (3,0). The graph the the heat whose equation is x = 3 is displayed in the figure below.

In general, one equation of kind x = a represents a right line parallel to the *y*-axis and also intersecting the *x*-axis in ~ (a,0).
