Hi,

Line parallel to the line x-y+4=0 0r ( y = x+4,  highlight_green%28m=1%29 )

that passes through the point (-1, -3)

***Using point-slope form, y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29

 +y%2B3+=+highlight%281%29%28x%2B1%29

 y+3 = x+1

New Line (In Standard Form)

  x - y = 2

Parallel lines have the same form.
x-y=D
Use the point to solve for D.
-1-%28-3%29=D
-1%2B3=D
D=2

x-y=2
x-y-2=0
