Find the coordinates for graphing this system of equations x+3y=-15. y=-7

>> x + 3y = -15

>> y = -7

x + 3y = -15

x + 3(-7) = -15

x - 21 = -15

x = -15 + 21

x = 6

x = 6 , y = -7

coordinates (6,-7)

  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.
