Ummm... I hate to tell you this, Anika, but it seems like none of those points fall on that line... Are you sure that that's the correct equation?

Okay so now that we know that the equation is y=5x-6, we can solve... Oh, and the first pair of points should be (-1, -11), just saying.

 

So, we have our equation. What we do is plug stuff in and see if it's right. So, with the first one:

$$y=5x-6, y=-11, x=-1$$

Now let's plug stuff in:

$$-11 = 5(-1)-6\Rightarrow-11=-5-6\Rightarrow-11=-11$$

So, that's true. Let's check the next two:

$$4=5(2)-6\Rightarrow4=10-6\Rightarrow4=4$$

That's right too. Now let's check the last one:

$$-1=5(0)-6\Rightarrow-1=0-6\Rightarrow-1=-6$$

Well, that's not right, obviously! So, that point is NOT on the line y=5x-6.
