Average Gradient (Grade 11 NSC Matric Mathematics): Flashcards

Overall rate of change between two points on a curve

Straight line passing through two points on a curve

$\frac{y_2 - y_1}{x_2 - x_1}$

Change in y divided by change in x (average gradient mnemonic)

$\frac{f(a+h) - f(a)}{h}$

Tangent line

Gradient at a point when two points coincide

Function is decreasing

$2a + h$

$-4$
