Graphing Lines (Leaving Cert Mathematics): Flashcards

Point where line crosses x-axis (where $y = 0$)

Point where line crosses y-axis (where $x = 0$)

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

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

$x = a$ (where $a$ is a constant)

The y-axis

$y = b$ (where $b$ is a constant)

The x-axis

No constant term in equation

$(0, 0)$ - the origin

Substitute coordinates into equation; if it holds true, point is on line

Two points
