Yes, since y changes proportionally with x.
no
Yes, y=-2+x is a linear function.
Only if it's a function.
It is not a linear function because it is missing x as the input variable
y=x+4
no
Yes, y=-2+x is a linear function.
Only if it's a function.
It is not a linear function because it is missing x as the input variable
Yes.
y=x+4
Yes, y=x-4 is linear, since the highest power on x is 1 (y = x1-4)

No, the function ( f(x) = x^2 - 4 ) is not a linear function. It is a quadratic function because it includes the term ( x^2 ), which makes its graph a parabola rather than a straight line. Linear functions have the general form ( f(x) = mx + b ), where ( m ) and ( b ) are constants.
It is linear. The highest power is 1 (x = x1, y = y1) so it is linear.
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.
