Revision (Grade 12 NSC Matric Mathematics): Flashcards

$y = mx + c$ or $y = ax + q$

Gradient (slope) of the line

Y-intercept (where line crosses y-axis)

$y = ax^2 + bx + c$

Opens upward ("smiles")

$x = -\frac{b}{2a}$

$y = b^x$ where $b > 0$ and $b ≠ 1$

$(0, 1)$ because $b^0 = 1$

When $b > 1$

$y = 0$ (the x-axis)
