Linear Functions (HSC SSCE Mathematics Advanced): Flashcards

$y = mx + c$ where $m$ and $c$ are constants

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

Steepness of a line and rate of change

$y = mx + c$

The gradient

The y-intercept

Slopes upward from left to right

Slopes downward from left to right

$ax + by + c = 0$

Set $y = 0$ and solve for $x$
