Measure it. It LOOKS straight - you’ve got a steady hand, but but you might be one of them AI-generated video-stars, hoisting all KIND of fakery. If you wanted to prove how straight the line was, you could have measured it. You made a pretty good job of it, even without using the tape measure you had (coff) right there.
