Is y=-x^2-1 linear or non linear

Non-linear

Step-by-step explanation:

The equation y = -x^2 - 1 produces a graph that is curved, which is non-linear.

An equation like y = -x - 1 would be considered linear because it produces a straight line.

The difference between linear and non-linear is as follows:

- Linear is a straight line with increasing/decreasing y values

- Non-linear is a curved line with a non-constant rate.

I attached a picture of the graph of y = -x^2 - 1
