Start by finding the b or the y-intercept.
This is the point where the line crosses the y-axis.
Our y-intercept is (0,5) or just 6.
From here, we look for clear cut points on the line.
Notice that if we go down 1 unit and to the right 3 units,
our point will end up exactly in the middle of the cross.
So our slope is -1/3.
So the equation is -1/3x + 5.
