lines in space neither the parametric equations nor the symmetric equations of a given line are unique
{"Image DocumentName": "Lines in Space Neither the parametric equations nor the symmetric equations of a given line are unique.", "Image ImageDescription": "For instance, in Example 1, by letting t = 1 in the parametric equations you would obtain the point (3, 2, 0). Using this point with the direction numbers a = 2, b = 4, and c = \u20134 produces the parametric equations. x = 3 + 2t, y = 2 + 4t, and z = \u20134t.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
