Question

What is the equation of the trend line in the scatter plot?

Someone pls help I will pay if you get it right

Answer 1

Given:

The graph of a trend line.

To find:

The equation of the trend line.

Solution:

From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:

`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)`

`y-4=(7-4)/(9-0)(x-0)`

`y-4=(3)/(9)(x)`

`y=(1)/(3)x+4`

Therefore, the equation of the trend line is
`y=(1)/(3)x+4`.
