Question

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

Answer 1

25-3/10-1 which is 22/9

Answer 2

The slope of a trend is equal to
`m=(22)/(9)`

Explanation:

we know that

The formula to calculate the slope between two points is equal to

`m=(y2-y1)/(x2-x1)`

we have

`A(1,3)\ B(10,25)`

Substitute the values

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

`m=(22)/(9)`
