Answer:
y = 1/3x - 4
Explanation:
We know slope-intercept form is y=mx+b, where m is the slope and b is the y=intercept. We can see that the line intercepts the graph at -4, so we can substitute +b for -4.
y=mx-4
Then, we need to find the slope. By taking the points (0,-4) and (3,-3), we can see that the rise is 1, and the run is 3. Rise over run is the slope, so we have 1/3 as a slope. Substituting the slope, we have the correct form.
y=1/3x-4
