Answer 1

Step-by-step explanation

Eq is

y = -7

and distance from x - axis is 7 unit.

Step by step Now:

let That line be,

y = mx + c

and it is || to x-axis such that,

y = 0

If two lines are || then slope of both lines are equal to each other.

So, slope of x-axis, is 0

then on putting, m = 0 in that line, we get

y = 0 + c = c

and line passing through pt. (5,-7) then it must satisfy the eq of line,

y = -7 = c

So, the asked equation is,

y = -7

and distance from x - axis is always 7 unit.
