Find the equation

Given, A line which is perpendicular to x–axis and having intercept – 2.

To Find: The equation of the line.

Formula used: The equation of line is [y – y₁ = m(x – x₁)]

Explanation: Here, The line is perpendicular to the x–axis, then x is 0 and y is – 1.

So, The slope of line is, m =

m =

Since, It is given that x–intercept is – 2, so, y is 0.

Coordinates of line are (x₁, y₁) = (– 2, 0)

The equation of line = y – y₁ = m(x – x₁)

By putting the values, we get

y – 0 = (x – (– 2))

x + 2 = 0

Hence, The equation of line is x + 2 = 0
