In a function, y varies inversely with x. The constant of variation is 4. Which table could represent the function?
1 answer:
I don't see a table but I can give you the means to answer it yourself. The inverse function is represented by this: 
where k is your constant. You are given a k value of 4. If you solve this for k then you will get xy=4. In your tables, multiply your x value by your y value within your coordinate points and if you get a product of 4 each time you multiply x by y, then that table is your answer.

After the translation 4 units down
The rule of translation is (x, y) to (x , y-4)
The graph will be as following
============================================================================
For the graph of the triangle:
D = ( 4 , 0) , B = (6 , -2) and C = ( 10 , -2)
it is required to graph after translation 7 units left and 8 units up
So, for each point add ( -7 , 8 )
So,
D' = ( -3 , 8) , B' = (-1 , 6 ) and C' = ( 3 , 6)
the graph will be as following:
