Hope this helps

To solve

, we need to find a common denominator. If we multiply

by

, we get

. The reason we can do this is because two over two is really just equivalent to 1, and multiplying a number times one equals the original number. So if you're subtracting

from

, you have

.

It would x - 4 = y because tge opposite reciprocal of -1 is 1 and so using point slope form y + 2 = x - 2 and when simplified youll get x - 4 = y.

**Answer:**

k = ± 3

**Step-by-step explanation:**

Isolate the absolute value by dividing both sides by 3

| 3k | = 9

The value inside the bars can be positive or negative, thus

3k = ± 3 ( divide both sides by 3 )

k = ± 3
