The x - value represents time. Since x = 0 is 6 p.m., x = 1.25 means 1 hour and 15 minutes past 6 p.m., which is 7:15 p.m. The y - value represents the number of people in the music hall. The point is on a line of best - fit, so it gives an approximate value.

At 7:15 there were approximately 142 people in the music hall.
