D They all have negative slopes.

E They all cross the y-axis at 0.

The characteristics of nonvertical lines that make slope-intercept form (\(y = mx + b\)) a good choice when writing an equation for this type of line are:

A. They all have a constant rate of change.
B. They all cross the y-axis.

Therefore, the correct choices are A and B.

The characteristics C, D, and E are not universally true for all nonvertical lines, as the slope can be either positive or negative, and the y-intercept (b) can be any value, not just 0.
