Is the function y = -10 – x/4 linear or nonlinear?

The function ( y = -10 – frac{x}{4} ) is linear.

A linear function can be written in the form ( y = mx + b ), where ( m ) is the slope and ( b ) is the y-intercept. In this case, we can rearrange it to ( y = -frac{1}{4}x – 10 ), which fits the linear form. The graph of this function would be a straight line.
