Hi there!
Since the slope of a lime that is parallel is always the same, the answer is a. -1.
Since the slope of this equation is -1, the slope of any other parallel line is the same (or else the lines would intersect and not new parallel anymore).
Hope this helps!

Answer:
Concept: Percentage Addition
- Your original price is 7.70
- It increased by 60%
- Hence you do 7.70 * .60 = x
- Whatever you get from (3) you add it to 7.70+x to get your final price

Two immediate observations:
(1) Clearly, we can't have

, since that would make both the rational and the square root terms undefined.
(2) If

is real, then

only exists if

. This means that for

to exist, we require

.
If

, then we don't have to worry about

ever taking on a value of -2.
