Answer:
Raul's claims are not correct
The equation of the graph is
Step-by-step explanation:
Part a)
we know that
The fact that the data form a straight line does not imply that it is a proportional relationship. In order for it to be a proportional relationship, in addition to the fact that a straight line must be formed, it must pass through the origin.
In this problem the graph shows a proportional relationship because the data forms a straight line and passes through the origin (0,0)
therefore
The claim that the graph shows a proportional relationship because the data forms a straight line is not correct
Part B)
<u>Find the slope of the straight line</u>
Let
The formula to calculate the slope between two points is equal to
substitute the values
therefore
The claim that he reads 1.5 pages per minute is not correct
Part C)
The equation of the graph is equal to
