How would this work? the graph is kinda weird
klasskru [66]
The graph is labeled on the side(Followers) and on the bottom(Days). With the table, you count the lines to find the point you need to be on. For example, the 1st day Trey got 120 followers. You would find #1 on the bottom part of the graph, and then proceed to find 120 on the side of the graph. Trace towards the middle, and where they meet is where you would place the point.
