Answer:

Is not proportional

Explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
k=(y)/(x) or
y=kx

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

y=10+2x

This is the equation of a line in slope intercept form

where

$m=2\\b=10$

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
