The slope = -5/4
The y-intercept = +1 (pay attention to the positives and the negatives)
To graph, start at the point (0, 1)
Then (sense slope is essentially rise over run), you go down 5 units (sense its a negative 5) and 4 units to the right.
Your next point would be (4, -4)
Next, draw a straight line , connecting the two points and beyond.
Hope this helps!!
