Parallel and Perpendicular Lines matching game
Tap an item on the left, then its partner on the right. Beat your best time. Matching games train quick recall, which is exactly what tests ask for.
The pairs (answer key)
A line with slope 3/5 ↔ A perpendicular line has slope −5/3
A line with slope −4 ↔ A perpendicular line has slope 1/4
A line perpendicular to y = 2 ↔ A vertical line, like x = 6
y = x + 5 and y = x − 7 ↔ Parallel
y = x/3 + 5 and y = −3x − 2 ↔ Perpendicular
y = 6x + 2 and y = −6x + 2 ↔ Neither
y = 4x − 1 and 2y = 8x − 2 ↔ The same line
