Answer:
2
Offmind's Step-by-step explanation:
The Mode of a data set (line plot in this case) is the number which occurs most often. The line plot here shows the most x's on the number 2 than any other number so the mode is in fact, 2.
Bonus Fact: In another case, if there had been two numbers with the same amount of x's then those would both be considered the mode!
