Question

What is the equation of this trend line? RE Enter your answers b y filling in the boxes.

Answer 1

Answer:

$K=-2J+28$

Step-by-step explanation:

step 1

Find the slope of the line

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

$m=\frac{k2-k1}{j2-j1}$

we have the points

(2,24) and (6,16)

substitute in the formula

$m=\frac{16-24}{6-2}$

$m=\frac{-8}{4}$

$m-2$

step 2

Find the equation of the line in slope intercept form

$K=mJ+b$

we have

$m=-2$

$b=28$ ----> the k-intercept is the point (0,28)  see the graph

substitute

$K=-2J+28$
