It is not a linear function because it is missing x as the input variable

Yes, y=-2+x is a linear function.

Only if it's a function.

No. 1a and 3d are linear, but 2bc is not. ■

Yes.

Yes.

No, it is not.

Yes.

The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.

It is a linear function. That is to say, it is a function representing a straight line in the coordinate plane.

A linear relationship. Added: And a function.

Yes, y=-5x+3 is a linear function. We know that by two factors. First, if you plot the function, you find that it draws a straight line, hence the term linear. Second, if you inspect the non-constant terms, you find that all of the are in the first power, i.e. there are no "squareds", "cubes", square roots", etc. This also makes it s linear function.

Y = 2X + 8 is a linear function of the form, Y = mX + c. A line.

It is linear.

Yes.y = 2x + 3 is a linear function, meaning that, if you were to plot the function on a graph, it would create a straight line.

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.

Yes, it is.

Yes, y = 3+x is linear.

It is the linear equation of a straight line.

Yes, it is a linear straight line equation.

Yes it is.
