Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
6/12 and 4/8 are equal fractions, as, when simplified, they share a simplified fraction.
Note that what you do to the denominator, you do to the numerator. Find common denominators for both fractions:
(4/8)/(2/2) = 2/4
(6/12)/(3/3) = 2/4
As you can tell, when they share a common denominator (4), the numerators are the same as well (3).

Answer: left 7 units, up 4 units, and vertical compression
Step-by-step explanation:
Given
The function is 
First shift it to the left by 7 units, so the function becomes

Now compress it to make it one-third

Now, sift the graph upward by 4 units

Thus , the conditions are left 7 units, up 4 units, and vertical compression.
