Answer:
22/9
Step-by-step explanation:
The slope of a line can be found by using the slope formula
[tex]\frac{y_2-y_1}{x_2-x_1} \text{ where we have points } (x_1,y_1) \text{ and } (x_2,y_2) \text{ on the line }[/tex].
Or what I like to do is line up the points and subtract vertically, then put 2nd difference over 1st difference. Like so:
( 10 , 25)
- ( 1 , 3)
----------------
9 22
So the slope is 22/9.
You could have done it the other way too. That is:
(1 , 3)
-(10 , 25)
------------
-9 -22
So the slope is -22/-9 or just 22/9.
Answer:
The slope of a trend line is:
[tex]m=\frac{22}{9}[/tex]
Step-by-step explanation:
The slope m of a line is calculated using the following formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
For any pair of points [tex](x_1, y_1),\ (x_2, y_2)[/tex] that belong to the line
In this case the points are (1,3) and (10,25)
Therefore the slope is:
[tex]m=\frac{25-3}{10-1}[/tex]
[tex]m=\frac{22}{9}[/tex]
