Question

7. Write the equations of the straight lines parallel to X - axis and (i) at a distance of 3 units
the X - axis and (ii) at a distance of 4 units below the X -axis.​

Answer 1

Step-by-step explanation:

(1) equation of line parallel to x axis at a distance of 3 units is y = 3 or y - 3 = 0

(2) equation of line parallel to x axis and at a distance 4 units below x axis is y = -4 or y+4 = 0

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.
