Linear Models (VCE SSCE Mathematical Methods): Flashcards

Situation where one quantity changes at a constant rate

$y = mx + c$

Gradient (rate of change)

Y-intercept (starting value)

Linear model showing how total costs depend on quantity

Constant amount that doesn't change (y-intercept)

Amount that increases with each unit (gradient × quantity)

Moving away from reference point (distance increasing)

Moving towards reference point (distance decreasing)

Speed (always positive)
