The cumcutative property of addition
You can do this by taking away the second equation from the first to get rid of the x terms so:
7x - 7x = 0
-5y - -9y = - 5y + 9y = 4y
22-6 = 16
So you are left with the equation:
4y = 16
Divide both sides by 4 to find y
y = 4
Answer: y = -1/3x -5 (4th option is correct)
Step-by-step explanation:
- The slope of a perpendicular line is opposite reciprocal --> -1/3
- Find b.
- -4 = -3(-1/3) + b
- -4 = 1 +b
- -5 = b

Explicit rule is a(n) = 9*(-5)^(n-1)
The recursive rule is a(n) = -5*a(n-1); a(1) = 9
The first term is 9. Each new term is found by multiplying the previous term by -5
We can see this when we raise -5 to a whole number power. Eg: 9(-5)^3 = 9*(-5)*(-5)*(-5)
Answer: Choice D
