Question

The equation of a line which is parallel to x axis at a distane of 3cm from the origin is
(A) x=3 (B)y=3 (C) x+3=0 (D) y+3=0

Answer 1

Answer:

The equation of line parallel to X-axis is y=k ; K is the distance from origin as shown,

According to question the line at distance 3 from origin can be in both the direction of Y-axis and hence the equation are y=±3 or

y=−3 and y=3

Answer 2

Step-by-step explanation:

let equation y=mx+c

because point (0,3) lies on the line

hence 3=0+c

c=3

again this line parallel to x-axis

so slope m=0

hence the equation of line is y=3
