What does a graph look like if there is a proportional relationship?

like this, somewhat :)

It is an inverse proportional relationship if the graph … is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.

answer: the answer is d

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
