Answer:
y = -x - 2
Step-by-step explanation:
Simplifying the equation of our line;
y - 1 = (x + 2)
y = x + 3
The slope of our line is 1
The slope of the perpendicular line(s) must be -1 (the product of slopes of two perpendicular lines = -1)
The line whose slope is -1 (from the choices) is the one whose equation is:
y = -x - 2
