Without an equality sign it is not an equation.
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.
-1
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' .

In one word 'NO' Since it is and 'x^(2)' term, this will make a parabolic curve, not linear (straight line).
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.
Yes, a linear equation in t.
