Question

the equation of a line parallel to x axis and at a distance 3 units below it is​

Answer 1

Answer:

x+2y−3=0........................(i)

2x−y+5=0.......................(ii)

1× (i)+2× (ii), we get

⇒5x+7=0

⇒x=

−7

putting value of x in (i), we get

and slope of y−x+10=0⇒y=(x−10) is =1

Therefore, Equation of the line will be,

Any straight line parallel to x−axis is given by y=k, where k is the distance of the line from x−axis. Here k=−3, because it is below x axis then the equation of the line is y=−3.
