3) This is definitely a positive association, but the question is - is it linear? 
Since a somewhat straight line can be drawn through the points, it is linear. 

<span>Answer: positive linear association 
</span>
4) Find the slope using the formula 
m =  \frac{y2 - y1}{x2 - x1}

m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out

Oh no! It seems that their is not a pattern in the association, so its nonlinear!

Answer: Negative nonlinear association

5) <span>m = \frac{y2 - y1}{x2 - x1}
m = 80 - 66/ 5 - 3 
m = 14/2
m = 7

Positive! But is it linear??
Let us draw a graph this time. 

I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!

Answer: Positive nonlinear association
