Is anyone available to check these for me?
#1
Since your new line is to be parallel to y = -x - 2
then it must clearly start as y = -x ...... as well
let new one be y = -x + b, but (2,-2) is on it, so
-2 = -2) + b
b = 0
new one is y = -x
#2, correct
#3, the given line x = -3 is a vertical line
so the vertical line passing through (4,2) must be
x = 4, which is none of the given choices
TYPO!
