Answer:

  y = -1/3x -1

Step-by-step explanation:

The line has a run of 3 units (to the right) for each rise of -1 unit. The slope is ...

  m = rise/run = -1/3

The y-intercept is the marked point on the y-axis: b = -1.

Then the slope-intercept equation is ...

  y = mx +b . . . . . . . slope m, y-intercept b

  y = -1/3x -1
