Line Segment Division/Graphing Lines (Leaving Cert Mathematics): Flashcards

$y = mx + c$

Slope

$y$-intercept

$y - y_1 = m(x - x_1)$

When slope and a point on the line are known

$ax + by + c = 0$

Rise over run

Rewrite equation to slope-intercept form $y = mx + c$

The $y$-intercept

$y = k$

All points have the same $y$-coordinate

$x = k$

All points have the same $x$-coordinate
