Straight-line graphs 1 (AQA GCSE Maths): Flashcards

$y = mx + c$

Gradient (steepness of line)

Y-intercept (where line crosses y-axis)

Line slopes upwards from left to right

Line slopes downwards from left to right

$x = 0$

$\frac{\text{rise}}{\text{run}}$

Choose x values, substitute, plot points, join with ruler

Where line crosses y-axis, read y-coordinate

Easily identify gradient and y-intercept
