Answer:
440 Meters
Step-by-step explanation:
The question asks what his altitude was at the beginning, the beginning is the y-intercept and the y-intercept is 440 according to this graph so that's why the answer is 440.
Answer:
2.5
Step-by-step explanation:
I think it's reflected and dilated.
Answer:
Table 3 has a greater y intercept
Step-by-step explanation:
See attachment (1) & (2) for graph and tables
First, we have to determine the y intercept of the graph
The y intercept of any graph or table is the corresponding value of a point where 
In the attached graph.
when 
So:

Next, we determine the y intercept of each table.
Recall that: The y intercept of any graph or table is the corresponding value of a point where 
For table 1:

For table 2:

For table 3:

By comparison, the y intercepts of tables (1) & (2) are less than the y intercept of the graph because: 3 and 2 are less than 4
However, the y intercept of table 3 is greater than the y intercept of the graph because 5 is greater than 4.
<em>Hence, table 3 has a greater y intercept</em>
