Straight Lines and Gradients (AQA GCSE Maths): Flashcards

Contain only $x$ and $y$ terms, no higher powers

$x = a$

$y = a$

$y = x$

The steepness of a line

$\frac{\text{Change in y}}{\text{Change in x}}$

Slopes uphill (rises from left to right)

Slopes downhill (falls from left to right)

$y = ax$ (where $a$ determines the gradient)
