Answer -
Given: A line which isperpendicular to x–axis and having intercept –2
By using the formula,
The equation of line:[y – y1 = m(x – x1)]
We know that, the lineis perpendicular to the x–axis, then x is 0 and y is –1.
The slope of line is,m = y/x
= -1/0
It is given thatx–intercept is –2, so, y is 0.
Coordinates of lineare (x1, y1) = (–2, 0)
The equation of line =y – y1 = m(x – x1)
Now, substitute thevalues, we get
y – 0= (-1/0) (x – (– 2))
x + 2 = 0
∴ The equation of lineis x + 2 = 0
