Answer:
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
