An herbalist has 20 oz of herbs costing $4 per ounce. How many ounces of herbs costing $2 per ounce should be mixed with these 20 oz of herbs to produce a mixture costing $2.80 per ounce?

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.
