Question

What is the slope of a trend line that passes through the points (1, 3) and (10, 25)?
​

Answer 1

The slope of the line is
`(22)/(9)`.

Explanation:

Given,

The two points are (1,3) and (10,25).

To find the slope of the lines passing through the points.

Formula

If a line passes through (
`x_(1) ,y_(1)`) and (
`x_(2) ,y_(2)`), the slope will be m =
`(y_(2) -y_(1) )/(x_(2)-x_(1) )`

Now,

Putting,
`x_(1)=1, y_(1)=3, x_(2)=10, y_(2)=25` we get,

m =
`(25-3)/(10-1)` =
`(22)/(9)`
