PLEASE HELP!!!! I DONT UNDERSTAND THIS.
The table and the graph below each show a different relationship between the same two variables, x and y:

A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 4 comma 80 and 5 comma 100 and 6 comma 120 and 7 comma 140. On the right of this table is a graph. The x-axis values are from 0 to 10 in increments of 2 for each grid line. The y-axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2 comma 70 and 4 comma 140 and 6 comma 210 and 8 comma 280 is drawn.

How much more would the value of y be on the graph than its value in the table when x = 12?
20
