The equation of a line parallel to the y-axis is is the equation of a vertical line since the vertical line lies along the y-axis. The equation that represents a line which is parallel to the y-axis is x = -8
Equation of a line
A line is defined as the shortest distance between two points. The formula for finding the equation of a line in slope-intercept form is given as;
y = mx + b
The point sloe form of the equation is given as y-y1 = m(x-x1)
where
- m is the slope
- b is the intercept
- (x1, y1) is any point on the line
The equation of a line parallel to the y-axis is is the equation of a vertical line since the vertical line lies along the y-axis.
The equation of a vertical line is expressed in the form x = a where a is the x-intercept.
Therefore the equation that represents a line which is parallel to the y-axis is x = -8
