What do you think?

If I knew I wouldn't be asking for help.

3mar · Answer

So can you test the first point of the first set?
satisfies the equation (y = 6x – 4) or not?

bribri423 · Answer

nope

3mar · Answer

OK.
Let me shoe you Step by step.


We have such point (0, –4)
x=0     and           y=-4

and the equation is : y = 6x – 4

substitute with x=0 and y=-4 in the above equation!

What you got?

bribri423 · Answer

I think that its the first one, {(0, –4), (1, 2), (3, 14)}

3mar · Answer

all these point satisfy the equation? did you test them all?

bribri423 · Answer

yes
i think so
