possible,

Answer 1

Answer:

2 equation are possible but please mark as brianlist

Answer 2

Answer:

→ Let AB be a straight line parallel to x-axis at a distance b units from it. Then, clearly, all points on the line AB have the same ordinate b. Thus, AB can be considered as the locus of a point at a distance b from x-axis and all points on the line AB satisfy the condition y = b.

• Thus, if P(x, y) is any point on AB, then y = b.
• The equation of x-axis is y = 0, since, x-axis is a parallel to itself at a distance 0 from it.
• If a straight line is parallel and below to x-axis at a distance b, then its equation is y = -b.
