Two students were asked to graph the rational number -7.1. amy states that the number is between -8 and -7, but laura states that the point is between -7 and -6. how can you determine which student is correct?

Amy is correct, -7.1 is between -7 and -8.  We know this because in order for it to be in between -6 and -7, the number would have to be a decimal with a whole number of 6 (for example, 6.3 or 6.7).  But -7.1 has a whole number of 7 so it is in between -7 and -8

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
