Question

What is the equation of the line, in general form, that passes through the point (-1, -1) and is parallel to the line whose equation is x + y = 3?

answers
x - y + 2 = 0
x + y + 2 = 0
x + y - 2 = 0

Answer 1

it is parallel to y = -x+3 so slope of parallel lineis -1


use point slope form

y - (-1) = -1(x - (-1))

y + 1 = -(x+!)

y + 1 = -x - 1
y = -x - 1 - 1

y = -x - 2

Answer 2

or rewrite as x +y + 2 = 0

Answer 3

thank you
