What is the slope of the line that contains these points?
x 39 40 41 42
y 36 29 22 15

-7

Step-by-step explanation:

Use this formula for finding the slope:

Δy/Δx=y1-y2/x1-x2

Now get 2 points, (39, 36); (40, 29)

36-29/39-40= 7/-1= -7

So the slop is -7

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
