Een voorproefje

1. What is the distance formula between two points A(x1, y1) and B(x2, y2) in a 2D Cartesian plane?(x2 − x1) + (y2 − y1)(x2 − x1)² + (y2 − y1)²Square root of ((x2 + x1)² + (y2 + y1)²)Square root of ((x2 − x1)² + (y2 − y1)²)
2. What is the slope (gradient) m of a line passing through points (1, 2) and (3, 8)?2346
3. Do two non-vertical parallel lines in a plane have slopes whose product equals -1?No, parallel lines have equal slopesNo, unless the slope is zeroYes, parallel lines have inverse slopesYes, parallel slopes multiply to -1
