Without an equality sign it is not an equation.
Yes.
A linear relationship. Added: And a function.
A linear equation is one which represents a straight line. When drawn (y plotted against x), a degree 1 polynomial produces a straight line.
y = 2x + 1 IS a linear equation!
Without an equality sign it is not an equation.
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' .

The required condition is a*b ≠0. That is equivalent to the requirement that neither a nor b is 0.
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.

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}
