Y-y1=m(x-x1)
find slope
(y2-y1)/(x2-x1)
so
(-4,-1)
(3,-3)
slope=(-3-(-1))/(3-(-4))=(-3+1)/(3+4)=-2/7
y-(-1)=-2/7(x-(-4))
y+1=-2/7(x+4)
Answer:
Step-by-step explanation:
The question says that the fish population of an area is being tracked and a certain of 35 were collected,tagged and released.
Later another sample was collected and it revealed that 13% of those fishes caught were the ones tagged previously.
The estimated number of fishes in that area will be:
Let X= number of fishes available in that area
13 percent of fishes caught at the second sample collection were tagged
Number of fishes collected are 35
13/100×X= 35
X= 3500/13
X= 269
The number of fishes in the pond is around 269
if y=367
then you need to figure out this:
367=5x+287
so remove 287 from 367
367-287=80
Then divide by 5
80/5=16
so, x=16
Answer:
Multiply 4 by the difference of 10 and 3, then add 5
Divide the denominator from the numerator.
For example:
1/8 is the same as 1÷8
Then do long division:
_____
8) 1
You will get 0.125
