Question

This describes how much a line rises or falls between any two points on that line. Algebraically it is expressed as (y2 - y1)/ (x2 - x1) for the line passing through (x1, y1) and (x2, y2).
__________

Answer 1

That is Slope or Average Rate of Change.

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

This is the slope formula

Answer 2

True, slope

Answer 3

yep its slope
