Answer:

  y = -1/3x +5

Step-by-step explanation:

The graph crosses the y-axis at y=5, so that is the y-intercept.

The graph crosses the next grid line intersection point 3 units to the right and 1 unit down, so the slope is ...

  m = rise/run = -1/3

The slope-intercept equation is then ...

  y = mx + b . . . . . for slope m and y-intercept b

  y = -1/3x + 5
