Christopher keeps track of the number of people inside a music hall to attend a concert by looking at the number of scanned tickets. He plotted the data on the graph below, where x, equals, 0x=0 represents the time at 6 p.m., then drew a line of best fit. What does the point left bracket, 1, point, 5, comma, 160, point, 5, right bracket(1.5,160.5) on the line of best fit represent?
At 7:30, there were exactly 161 people in the music hall.
At 1:30, Christopher should expect about 160.5 people in the music hall.
