In the graph y= -4. To find that you'd look for 0 on the x axis and find where the line would meet on the y axis (0,-4).
In the graph x= 3. To find that you'd look for -2 on the y axis and find where the line would meet on the x axis (3,-2).
To estimate the outlier you'll want to look to see which seems out of line. (40,2) seems as if it does not belong.
To find if the correlation is negotiable or positive just remember that if it goes up your right it's positive and up to your left is negative. This seems to be going up to my right so it's positive.
Is it positive or negative-just as I explained in the last question this one seems to go up my left so it'd be negative.
For the last question if you look at the x to the bottom right it looks as if it's at 48 or 49. Let's say 49. (49,0). So you need to find x=50. Well because it's going down y would be less than 0. I think you could make a good estimate now.
I hope that helped.
