Answer:
x + y = -2
Step-by-step explanation:
Parallel lines have the same slope, so the line's slope will also be -1.
Plug in the slope and the given point into y = mx + b to find b:
y = mx + b
-5 = -1(3) + b
-5 = -3 + b
-2 = b
Plug this and the slope into y = mx + b
y = mx + b
y = -x - 2
Put this into standard form by moving the x to the other side:
x + y = -2
So, x + y = -2 is the equation in standard form
