Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 5 = - 3(x + 2) ← is in point- slope form
with slope m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
and (a, b) = (6, - 1), hence
y - (- 1) = (x - 6), that is
y + 1 = (x - 6) → C
