The proportional relationship between x and y is;
x 7 14 28 35
y 1 2 4 5
The correct option is D.
Proportional relationships;
Proportional relationships between x and y satisfy the following equation;
[tex]\rm y=kx[/tex]
Where k is some constant.
Rearranging the equation;
[tex]\rm y=kx\\\\k=\dfrac{y}{x}[/tex]
Then,
The proportional relationship between x and y is;
[tex]\rm k = \dfrac{y}{x}\\\\\rm When \ x= 7 \ and \ y= 1\\\\K=\dfrac{1}{7}\\\\\rm When \ x= 14 \ and \ y= 2\\\\K=\dfrac{2}{14}=\dfrac{1}{7}\\\\\rm When \ x= 28 \ and \ y= 4\\\\K=\dfrac{4}{28}=\dfrac{1}{7}\\\\\rm When \ x= 35 \ and \ y= 5\\\\K=\dfrac{5}{35}=\dfrac{1}{7}[/tex]
Hence, the proportional relationship between x and y is the correct option is D.
