Answer:

3rd and 4th options

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{m} }{a^{n} }$ ( n > m )

= $\frac{1}{a^{(n-m)} }$

Then

$3^{4}$ ÷ $3^{9}$

= $\frac{3^{4} }{3^{9} }$

= $\frac{1}{3^{(9-4)} }$

= $\frac{1}{3^{5} }$

= $\frac{1}{243}$

h=-2
k=-1

So vertex should be at (h,k)=(-2,-1)

Answer:

y = 7/8x + 1

Step-by-step explanation:

According to y = mx + b, whereas b is the y-intercept

so if b is positive, b has to be larger than 0

A non-proportional graph is a straight line that does not go through the origin so
