Q. Find the equation of straight line parallel to y axis and at a distance of 2 units.
Characteristics of y-axis line: Understand the characteristics of a line parallel to the y-axis.A line parallel to the y-axis is a vertical line. Vertical lines have an undefined slope and their equation is in the form of x=a constant value. This constant value represents the distance from the y-axis.
Determine constant value: Determine the constant value for the equation of the line.Since the line is at a distance of 2 units from the y-axis, the constant value will be the x-coordinate of every point on the line. As the line is parallel to the y-axis, this distance is the same for all points on the line.
Write line equation: Write the equation of the line.The equation of the line parallel to the y-axis and 2 units away from it is x=2. This equation means that for any value of y, the value of x will always be 2.
