Answer:

<h2>C. positive association</h2>

Step-by-step explanation:

Positive and negative association describe a relation between variables about a scatter plot.

A positive association happens when one variable increases while the other one also increases.

A negative association happens when one variable decreases while the other variable increases.

It's important to know that the variable that always increases is the independent variable, it increases no matter what.

In this case, we could say that we have a positive association, because while <em>x </em>increases, <em>y </em>also increases.

You could notice that there's some repetitive number. That's normal because a scatter plot doesn't describe a perfect linear relation at the beginning, actually, it's a bit messy, however, from such data we construct a linear relationship which is called "linear regression".

Therefore, the right answer is C.

Answer:

'x' and 'y' have a positive association between them.

Step-by-step explanation:

We can see in the given data that as 'x' remains constant or increases by 1 unit, or two units in it's two consecutive values, in each of the cases 'y' increases by 1 unit.

Hence, 'x' and 'y' have a positive association between them.

Answer:

(1, 4)
(2, 8)
(3, 12)

Step-by-step explanation:

The ratios all have ...

first number : second number = 1 : 4

Using first numbers of 1, 2, 3, the second numbers can be found by multiplying these by 4. (1, 4), (2, 8), (3, 12)

You plot these (x, y) points the same way you plot <em>any</em> point on a coordinate grid. The first (x) value is the horizontal distance from the vertical axis. Positive is to the right. The second (y) value is the vertical distance from the horizontal axis. Positive is up.

Of course, the origin is where the horizontal and vertical axes meet. It can be convenient to find one of the coordinates on its respective axis, then use the other coordinate to find the point at the desired distance from that axis.

Usually, you would choose the axis on the basis of how easy it is to determine exactly where the coordinate lies. If the y-axis is marked every 5, for example, it might be hard to determine where a multiple of 4 will lie. Locating the x-coordinate on the x-axis may be an easier way to start.
