The new patio at Tonya's house is 5 yards long by 10 feet wide. She is going to cover the patio with square bricks that measure 1 foot on each side.
If each brick costs $4, how much will Tonya pay for the bricks?

  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.
