In normal line integration, from what I understand, you are measuring the area underneath (,)
f
(

,
y
)
along a curve in the -
x

Answer: $50
Step-by-step explanation:
30 × 10 = 40 ft² [garden area]
40 ÷ 25 = 1.6
1.6 ≈ 2
For the area of the entire garden, you need to buy two bottles of fertilizer.
25 × 2 = 50 [fertilization cost for the whole garden]
![\bf 10\cdot [2+(24-8)]\div 4\implies \stackrel{\mathbb{PEMDAS}}{10\cdot [2+(16)]\div 4}\implies 10\cdot [18]\div 4 \\\\\\ 180\div 4\implies 45](https://tex.z-dn.net/?f=%5Cbf%2010%5Ccdot%20%5B2%2B%2824-8%29%5D%5Cdiv%204%5Cimplies%20%5Cstackrel%7B%5Cmathbb%7BPEMDAS%7D%7D%7B10%5Ccdot%20%5B2%2B%2816%29%5D%5Cdiv%204%7D%5Cimplies%2010%5Ccdot%20%5B18%5D%5Cdiv%204%0A%5C%5C%5C%5C%5C%5C%0A180%5Cdiv%204%5Cimplies%2045)

Answer:
m = -1/2
Step-by-step explanation:
Recall that slope = (change in y) / (change in x).
Going from (−8,−1) to (−6,−2), x increases by 2 (because -6 - (-8) = 2), and
y decreases by 1. Thus, the slope here is
m = (change in y) / (change in x) = (-1) / 2 = -1 / 2
m = -1/2
