English: So you what you are left with is the equation of this line is x = ct − ct₀ + x₀ So if you do the same thing here so the equation of this line is if you do the same thing so t₀and what you are left with is this difference the slope is $t_{0} - t = \frac{t_{0}}{c\ t_{0}}(x - x_{0})$ so only difference is minus here, okay for this line.
Telugu: $t - t_{0} = \frac{t_{0}}{c\ t_{0}}(x - x_{0})$ అంటే ఈ x = x₀ − ct₀ లైన్ నుండి x = x₀ + ct₀ వరకు ఉంటుంది, కాబట్టి మీరు ఈ విధంగా చేస్తారు.
