Boris is ordering supplies for his company. he ordered 20 boxes of pencils and 32 boxes of pens. what is the ratio of boxes of pens ordered to boxes of pencils ordered?

  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.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

df =

both have same length
