Yes.
A linear relationship. Added: And a function.
y = 2x + 1 IS a linear equation!
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.

If you mean y = 4x+2 then it is the linear equation of a straight line
Yes.
The [ 2x + 1 ] represents a function of 'y' .

Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
Well, f(x) = 6x + 9 is a function of x {it passes the vertical line test}. but y = 6x + 9 is an equation {linear equation of two variables}
A linear equation.
Yes, y = 4x + 7 is a linear equation.
It is a linear equation in two variables, x and y. Any point on the line defined by the equation will satisfy the equation and conversely, any ordered pair that satisfies the equation will represent a point, in the Cartesian plane, will be on the line.
