Your drawing was much more helpful and informative than your statements in words and symbols.
I see that you want to evaluate (3/2)^2 times (8/15)^2.
You could combine these two expressions into one, as follows:
3*8
( ----------- )^2
2*15
This, in turn, can be simplified by reduction:
( 4/5 )^2. Expanded, this result gives us 16/25.
Next problem
----------------------------
( 9/4 )^4 * ( 4/3 )^3
9^4 4^3
First, focus on ( ------- ) * ( ----------- )
4^4 3^3
Now reduce 4^3 / 4^4: The end result is 1/4.
Reduce 9^4 / 3^3. To do this, rewrite that 9 as (3^2), resulting in:
3^8 / 3^3. The end result is 3^5.
Putting this expression back together, we get 3^5 / 4 (answer)
I think the correct answer should be 10
12 inches = 1 foot
12/6 = 2
5*2 = 10

Answer:
y = 3/2x -10
Step-by-step explanation:
The point-slope equation can be written ...
y = m(x -h) +k . . . . . for a line with slope m through point (h, k)
Using the given values, this is ...
y = (3/2)(x -6) -1 = 3/2x -9 -1
y = 3/2x -10 . . . . . slope-intercept equation
well, 84 divided by 3 is 28 and if you check that by multiplying 28 with 3 you get 84 so its 28
