Step-by-step explanation:

y = - x/3 + 4

Step-by-step explanation:

The equation of a line in slope-intercept form is y = mx + b. Where m is the slope and b is the y-intercept.

Because the line passes through the y-axis at 4, the y-intercept is 4.

The slope is -1/3 because the y moves down one unit as the x moves right 3 units.

Therefore, the answer is y = - x/3 + 4.
