I think that the best visual representation that the marine biologist would use is utilising a bar graph. A bar graph is composed of bars residing in a coordinate plane. In addition to that, the visual representation would most likely be used since the average weight and length of each trout coming from 5 different locations is compared.
Answer:
s = 9
Step-by-step explanation:
We can find the slope given two points
m = (y2-y1)/(x2-x1)
9 = (s-0)/(9-8)
9 = (s)/1
S = 9
2/7 = -3/a, (2/7)a = -3, a = -3/(2/7), so the answer would be -10.5 or -21/2
Answer:

Step-by-step explanation:

Apply distributive property.
