Answer: The answer is in the attached image
Step-by-step explanation: Using the formula Y=mx+b, B is the Y-intercept, and you graph it at the point (0,b) or, for this problem, (0,4) the Y-intercept is where the Y is when X=0. The slope is M in this formula, slope is calculated in rise over run. So for the slope negative one, every one block it moves to the right, it moves one block down.
