Question

Select all the true statements about the table.


x y
2 7
6 21
8 28
14 49


The slope is 3.5.



There is a proportional relationship between the variables x and y.



The slope is 7.



There is a linear relationship between the variables x and y, but not a proportional relationship.



The graph does not pass through the point (0, 0).

Answer 1

True statements:
- The slope is 3.5. (For example, (21−7)/(6−2) = 14/4 = 3.5.)
- There is a proportional relationship between x and y. (y/x = 7/2 = 3.5 for every row, so y = 3.5x and the line passes through (0,0).)

The other statements are false.
