Question
Obtain the equation of the line containing the point :
A(2, – 3) and parallel to the Y−axis
Solution
The equation of the line parallel to Y-axis is of the type x = a.
If this passes through the point (2, −3), then coordinates of this point satisfy this equation.
∴ a = 2
∴ the equation of the required line is x = 2.
