y = -5x + 1
[y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)]
So your slope is -5, and your y-intercept is 1 or (0,1)
Rise is the number of units you go up(+) or down(-).
Run is the number of units you go to the right.
Since your slope is -5 or , you go down 5 units, and to the right 1 unit.
