Answer:
Step-by-step explanation:
We can read off the y-intercept immediately; it is (0, 3), or just b = 3.
As we move to the right from (0, 3) to (4, 2), x increases by 4 and y decreases by 1. Thus the slope is m = rise/run = -1/4.
The equation of this line is thus y = (-1/4)x + 3. Unfortunately, your illustration doesn't show the fourth possible answer choice, which is likely to be the correct answer.
