Respuesta :

X goes by 1s

And y goes by 3s

Answer:

  • y = -3x + 18

Step-by-step explanation:

We can see:

  • x- values increase by 1 unit
  • y- values decrease by 3 units (slope is -3).

This is a linear relationship. Use point-slope form to find the equation:

  • y - 15 = -3(x - 1)
  • y = -3x + 3 + 15
  • y = -3x + 18
