How to Solve Find the largest increase in the graph.
From Friday to Saturday, the increase in time was greatest
Then find percent of increase to the nearest tenth
Difference
Original=
83-5252 ≈ 59.6
%
Advantages of Line GraphsCan visually see the trend of the data
Can see how data increases/decreasesCan compare two sets of data
Use a line graph with multiple sets of data
Disadvantages of Line GraphsHard to see the specific data points when the
scale is largeSometimes the scale can change the
appearance of the data
