Answer:

Step-by-step explanation:
Given:
The table is given as:
x 0 4 7 8
y 0 24 42 48
The relationship between 'x' and 'y' is a proportional relationship.
A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and 
A proportional relationship is given as:

Now, we plug in 'x' and 'y' values and find the value of 'k'.
Let 

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

Answer:
