Expert Answer:

 

 

 

straight line is equally inclined to the axes  that is its inclination  with x axis will be 135o

so slope is -1

Also  the line is  equidistance from the points (1,-2) and (3,4) i.e pass through the midpoint of  (1,-2) and (3,4)

i.e (2,1)

so line is y-1=-1(x-2)  =y+x-3=0
