zzr0ck3r · Answer

let x be the thing in table
example
4*0-2y = 8 implies y = -4
so one solution is (0,-4)

zzr0ck3r · Answer

do the same thing for 2, and -1.

whpalmer4 · Answer

So you take the value from the $x$ column, plug it into the equation, and solve for the value of $y$ that makes it true.  For example:

$$x=0$$$$4(0)-2y=8$$$$0-2y=8$$$$y=\frac{8}{-2} = -4$$

1 is not in your table

whpalmer4 · Answer

well, it is.  you were supposed to use x = 2 and x = -1, not x =-2 and x = 1..

whpalmer4 · Answer

because you aren't typing the correct values!  you need to use x = 2 and x = -1, not x = -2 and x = 1 as you have done with your answer

whpalmer4 · Answer

let's just stick to the original problem.

if x = 0, y = ?
if x = 2, y = ?
if x = -1, y = ?

whpalmer4 · Answer

Okay, those are the correct y values.  I do not know what format your system expects the answer to be, but the table has blanks for the y values.  You might try entering
-4, 0, -6  which would fill those blanks in order.  Or perhaps (0,-4), (2,0),(-1,-6) if that didn't work.
