In chemistry, particularly in context of a titration curve, linear region refers to parts of the graph where pH changes steadily with each addition of titrant.

Buffer Region: Part of the graph where small amounts of acid or base do not significantly alter pH; this can be compared to standing still on an escalator - your position doesn't change much even though time passes.
The measure of steepness or incline/decline in mathematical terms; similar to how fast or slow our imaginary escalator moves.
Gradient: In mathematics and physical sciences, gradient refers to how much one variable changes for each unit of change in another variable. In our escalator analogy, it's like the speed at which you're moving up or down.
