If Nico gave away some red circles and you would like to know how many red circles does he have left, you can calculate this using the following step:
Nico has 15 red circles.
n ... the number of red circles that he gave away
15 - n ... the number of circles that Nico still has
The correct result would be 15 - n.
<h3>a. slope =

</h3><h3>b. slope = m = positive = positive correlation = two sets of data increase together</h3><h3>Further explanation</h3>
Scatter plot shows the relationship between data
We can use Regression to make lines on the chart or you can also make lines with the principle as close as possible to all points
Regression

Because data is in the form of numbers from the hand span length and height of each of students. not displayed clearly, then we make a line directly by making points on the graph above and below the line as much as possible to be balanced
We specify 2 points that are crossed by a line, for example:
(6.45) and (8.60)
slope (m) = change in y / change in x

Slope has a positive value, and shows a positive correlation where the tendency of the number rises simultaneously, or can be concluded:
<em>tall students will have the long hand span length too</em>
