I need the answers of problem 1 and 2 please!!

Given the table represents a relation between x and y
The constant of proportionality = k
Where k = y/x
When x = 2, y = 10
So,
[tex]k=\frac{y}{x}=\frac{10}{2}=5[/tex]so, the constant proportionality = 5
2) the equation that describes the relation between x and y will be:
[tex]y=5x[/tex]
