Question

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

Answer 1

slope of a trend line that passes through the points (1, 3) and (10, 25) is
`(22)/(9)`

Explanation:

Formula of slope(m) for two points is given by:

`\text{Slope}(m) = (y_2-y_1)/(x_2-x_1)`

Given the two points:

`(1,3)` and
`(10, 25)`

Substitute these points in the given formula we have;

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

Simplify:

`m = (22)/(9)`

Therefore, the slope of a trend line that passes through the points (1, 3) and (10, 25) is
`(22)/(9)`
