Let's begin by listing out the information given to us:
[tex]y=\frac{2}{3}x+1[/tex]We proceed by defining a direct variation:
A direct variation refers to a mathematical expression in which a variable is equal to the product of a constant by the other variable. For example,
y = 3x; y = 1/3x; y = 2/3x
However, with the expression y = 2/3x + 1 , we further have "+1" which is separate from the coefficient of x & y. Hence, y = 2/3x + 1 is not a direct variation
