Introduction to Rates of Change (HSC SSCE Mathematics Advanced): Flashcards

Constant and equals the gradient $m$

Variable (not constant)

$y = mx + c$

The gradient (or slope)

The y-intercept

$ax^2 + bx + c = 0$ where $a \neq 0$

Rate of change at a particular moment in time

Gradient of the tangent line at that point

A straight line cutting through a curve at two points

$\frac{f(x + h) - f(x)}{h}$ where $h$ is small
