The sum of two intcgers is -6. If one of them is 2, then the other is (a) 4
(b) 4
(c) 8
(d) -8

  -8

Step-by-step explanation:    lets take the unknown number as x,

so we have, 2 + x= -6

                 by using transposition method, x= -6-2( positive becomes  

                                                                       negative when transpositioning)

      so, x= -8                      

option: d is correct

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
