Question

2. Write an equation that is perpendicular to y = -x +2 and goes
through the point (-3, 1).

Answer 1

x - y + 4 =0

Explanation:

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

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

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

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

Answer 2

Answer:x1-x2 - y1-y2
