6th Grade Math Help & FAST!!!

I only have 2 questions. 1 is multiple choice and one I have to type so please help. 1. Which set of output values correctly completes the function table? This is the function table: y= 2x - 4. Input (x) 6, 2, -4. Output (y) those three slots all have question marks. A. 8, 2, -12, B. 8, 0, 12, C. 8, 0, -12, and D. -8, 0, 12. Here is my 2nd question: Complete the function table and write the function rule. Input (x)the 5 numbers in the slots in the input (x) is 32, 14, ?, -2, and -10. Finally, the 5 numbers in the slots in output (y) are: 20, 2, -6, -14, and ?. Please help!
#1 B. and D. don't make sense because B doesn't have any negative numbers and in the function table there is one negative number. For D. even though there is a negative number the negative number they gave is in the wrong spot. So, it is either A. or C.
For number 1 I figured out the answer it is A. 8, 2, -12. JUST SOMEONE PLEASE HELP WITH THE SECOND QUESTION!!!!
if x=6, y = 2(6)-4 = 8
if x=2, y =2(2)-4 = 0
ifx=-4, y=2(-4)-4 = -12
So, choice is C
x: 32, 14, ? , -10
y: 20, 2, -6, -14, ?
so lets use the first and 2nd:
slope = (20-2)/(32-14) = 18/18 = 1
so y = 1x + b
sub in (14,2)
2 = 14 + b
b = -12
your equation is : y = x - 12
now use that to find the missing parts
Thanks for your help Reiny. I really appreciate it. :)
....You should know this, if you studied. You really shouldn't try to get answers from other peoples minds, you need it from your own mind. Try it, it MIGHT make you smarter, hon. (-.-)
