The base of a triangular plot of land is 1 km and the area is 1 km². What is the height of the plot?

  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.

i think asking google will you get the answer to that question

correct answer:

b.(19,-2)

so, converting firstly the mixed fractions to improper fractions and then "adding".
