Given: A line which is perpendicular to x–axis and having intercept –2
By using the formula,
The equation of line: [y – y1 = m(x – x1)]
We know that, the line is perpendicular to the x–axis, then x is 0 and y is –1.
The slope of line is, m = \( \dfrac{y}{x}\)
= \( \dfrac{-1}{0}\)
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)
Now, substitute the values, we get
y – 0 = (\( \dfrac{-1}{0}\)) (x – (– 2))
x + 2 = 0
The equation of line is x + 2 = 0
