parallel except for which So remember the line written and
- 00:13
standard form looks like this x plus b y equal
- 00:16
see so its slope is going to be negative a
- 00:21
overby right So to solve this problem we need to

- 00:23
calculate negative a over b for each line and pick
- 00:26
the one that doesn't match the rest right Well all
- 00:29
the other answer choices have the same slope Here we
- 00:31
go we've got to over negative six and then we've
- 00:34
got negative Three over nine got negative five over fifteen
- 00:37
got negative one over three there So yeah those are
- 00:39
all negative A third the odd man out on woman
- 00:42
out here is for x minus sixteen Why equals thirty
- 00:46
five which has a slope of negative one fourth so
