Answer: y = -3x + 7
Step-by-step explanation:
The formula for calculating equation of line that passes through two points is given by :
=
= 4
= 3
= -5
= -2
substituting the values into the equation , we have :
=
=
=
= -3
y + 5 = -3( x - 4 )
y + 5 = -3x + 12
y = -3x + 12 - 5
y = -3x + 7
Answer:
y=-3x+7
Step-by-step explanation:
y=mx+b is the formula you are going to end up once completed.
This, by given two points:
(4,-5) (3,-2)
= Point-Slope Intercept Form
= After subtracting both from above
-3 = is your slope, decreasing.
Substitute -3 for y=mx+b
y=-3x+b
Use one of the given points (any) to find what b equals.
(4,-5)
x y
-5=-3(4)+b
-5= -12+b
7=b
Final Equation:
y=-3x+7

Here's what I find.
Step-by-step explanation:
You have 800 deer at the end of Year 1, and you expect the population to decrease each year thereafter.
a) i) The recursive formula
Let dₙ = the deer population n years after the initial measurement.
For this situation,
a) ii) Definitions
n = the number of years from first measurement
r = the common ratio, that is, the deer population at the end of one year divided by the population of the previous year.
a) iii) First term of sequence
The first term of the sequence is d₀, the population when first measured.
b) The function formula
The formula for the nth term of a geometric series is
c) Value of d₀
Let n = 2; then d₂ = 800
