Question

What is the slope of the trend line?A. -4/3B. 4/3C. -2/3D. 2/3

Answer 1

In order to find the slope we will need two points where the line passes through

(3,18)=(x1,y1)

(12,6)=(x2,y2)

The formula to calculate the slope is

`m=(y_2-y_1)/(x_2-x_1)`

we substitute the values

`m=(6-18)/(12-3)=(-12)/(9)=-(4)/(3)`

The slope is -4/3

ANSWER

A. -4/3
