X+y=4
x-y=-2
who can solve it?

Adding both the equations

Substituting x=1 in equation 1

Therefore ( 1, 3) is the solution to equation.

dude   i don't even know. i've been trying for hours.

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.
