Respuesta :

Answer:x1-x2 - y1-y2

Step-by-step explanation:

Answer:

x - y + 4 =0

Step-by-step explanation:

y = -x +2 => x + y - 2 = 0

suppose: (d') ⊥ (d) ; (d): x + y - 2 =0

[tex](d'): \left \{ {goes through A(-3;1)} \atop {(d') perpendicular to (d): x+y-2 = 0 }} \right\\.[/tex]

=> (d'): x - y + 4 =0
