Find the di

Let y = mx + c be the line through points (-1, 2).

2 = m (-1) + c

c = m + 2

Thus, y = mx + m + 2 --------------- (1)

The given line as

x + y = 4 ------------ (2)

On solving these equations, we get, and Thus, is the point of intersection of lines (1) and (2).

Since, this point is at a distance of 3 units from point (-1, 2),

So, now using distance formula,    1 + m2 = m2 + 1 + 2m

2m = 0

m = 0

Therefore, the slope of the required line must be zero,

Hence, the line must be parallel to the x – axis.
