Answer:
300
Step-by-step explanation:
Using the table, we see that for each increase in x of 1, y increases 30. For example, from x = 4 to x = 5, it is an increase of 1 in x. The corresponding y values are 120 and 150, respectively, and that is an increase of 30. For an increase of 1 in x, y increases 30. For x to be 12, it has to increase 5 units from x = 7. That is the same as 5 increases of 1 unit in x. That corresponds to 5 increases of 30 in y. 5 * 30 = 150. When x increases 5, y increases 150.
We have x = 7, y = 210.
Add 5 to x and 150 to y:
For the table, x = 12; y = 360
Now we look at the graph.
Look at (0, 0) and (2, 110) on the graph. When x increases 2 (from 0 to 2), y increases 110 (from 0 to 110). Now look at the last point on the graph. It is (8, 440). We want the y-value for x = 12. Start with x = 8, y = 440. Add 2 to x and 110 to y: (10, 550). That gives us the y value for x = 10. We need the y value for x = 12. Again, add 2 to x and 110 to y. You get (12, 660).
For the graph, x = 12; y = 660
For x = 12, the graph's y value is 660, and the table's y value is 360.
To find how much more the graph value is than the table value, we subtract:
660 - 360 = 300
