The worldline of an object traveling at constant velocity will be slanted in a spacetime diagram. This is because the slope of a worldline represents velocity, and if the object is traveling at a constant velocity, the slope must be constant throughout the object's journey. A vertical line would represent an object at rest, and a horizontal line would represent an object traveling at the speed of light, both of which are not relevant to an object traveling at constant velocity.
