Q. 145.0( 1 Vote )

The equation of a A. x = 2

B. x = – 7

C. y = – 7

D. y = 2

Answer :

The equation of the straight line passing through the point (x1 , y1) with slope as m is

(y–y1) = m(x–x1)

So here the straight line passing through the point (2,–7) and parallel to x axis is

(y–(–7)) = 0(x–2) (Slope of the line parallel to x axis is 0)

⇒ y + 7 = 0

⇒ y = –7
