The angle to the left of angle 1 is 70, so angle 1 is equal to 180 - 70 - 70 which is 40,
Well, the unit rate in the table is approximately 1.143 (8/7)
So, the only lines which have unit rate in between 1.143 and 2 are Line 3 (1.5) and Line 4 (1.2).
I think it would best be displayed as a line plot.
Could you please formulate you answer better? So we can get a bette understanding
