Without an equality sign it is not an equation.
Yes.
A linear relationship. Added: And a function.
The equation that represents a linear function is A) ( y = -x + 9 ) and D) ( y = x - 9 ). Linear functions can be expressed in the form ( y = mx + b ), where ( m ) and ( b ) are constants. Options B) and C) represent quadratic and cubic functions, respectively, due to the presence of ( x^2 ) and ( x^3 ).
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.

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.
