For the proportional relationship, we have found that:

a)  The complete table is:

x        y

14      21

64      96

26      39

1         3/2

b) The equation is:

y = (3/2)*x

Working with proportional relationships.

A proportional relationship between two variables can be written as:

y = k*x

Where k is the constant of proportionality.

a) If we look at the table we can see the pair (14, 21), replacing that in the proportional relation we have:

21 = k*14

(21/14) = k

(3/2) = k

Then the equation is:

y = (3/2)*x

To complete the table, we need to evaluate the other values in the given equation.

for x = 64 we have:

y = (3/2)*64 = 96

for y = 39 we have:

39 = (3/2)*x

x = (2/3)*39 = 26

For x = 1 we have:

y = (3/2)*1 = 3/2

Then the complete table is:

x        y

14      21

64      96

26      39

1         3/2

b) We already found the equation, it is:

y = (3/2)*x

c) Just graph the above pairs (the ones from the table) and connect them with a line, an example can be seen below.
