00:03 All right, so your problem shows you a scatterplot, and it says what type of association does this graph show between x and y? and sometimes association can also be interchanged out for correlation, just as a side note.

00:18 So let's look and see what your options are.

00:20 We first start with linear or nonlinear.

00:23 Those are the two main words that come first, linear or nonlinear.

00:26 So let's look.

00:27 What is linear? line is a straight line.

00:31 So it has line in it.

00:32 It's a straight it would almost form a straight line right not a curve so non -linear would be a curve so like for example linear curve non -linear okay those are good examples so right here we have a straight line are pretty pretty straight line so it cannot be this one and it cannot be the last one strike those through cannot be it all right, so now we've got to see, okay, is it a positive or a negative? so what they mean by positive and negative, they mean a positive or negative slope.

01:17 So now that we got rid of our linear non -linear answers, let me erase really quick, and we'll talk about what the types of slope are, so it's a little refresher.

01:28 So we have four types of slope.

01:31 Here's my little sketch of each of them.

01:34 Make this one a little bigger.

01:35 Okay.

01:35 So we have positive sloping line.

01:42 We have negative sloping line...
