Answer:
x = 1 is the equation of a vertical line parallel to y-axis, as shown in attached figure.
Step-by-step explanation:
- As the equation of y-axis is [tex]x=0[/tex].
- If a line is parallel to y-axis i.e. x=0, then location of the that line will have at some distance - let say d - from y.
- The Distance d will be positive or negative depending on whether the line is located at the left side or right side of the y-axis.
- So, the equation of any parallel line to the y-axis and has an x-intercept will have an equation like x = a where a is the x-intercept.
- The slope of this vertical line will be undefined.
Therefore, from the above discussion, we can safely say that x = 1 is the equation of a vertical line parallel to y-axis, as shown in attached figure.
