Answer:
Is not proportional
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
[tex]y=10+2x[/tex]
This is the equation of a line in slope intercept form
where
[tex]m=2\\b=10[/tex]
The y-intercept of the line is the point (0,10)
That means, that the line not passes through the origin
therefore
The given equation is not proportional
