You can put this solution on YOUR website!
The y intercept is 4, which means the point (0,4) is on the graph. I'll label this as point A.
A = (0,4)
This is where the graph crosses the y axis.
From point A, move down 3 units and to the right 5 units to arrive at point B = (5,1)
The movement "down 3, to the right 5" comes directly from the slope of -3/5
slope = rise/run
slope = -3/5
rise = -3 means we drop 3 vertical units (y axis)
run = 5 means we move to the right 5 units (x axis)
As the diagram below indicates, the red line goes downhill as you read from left to right. This downhill direction is because of the negative slope.
After we have two points, we can draw a straight line through them
I used GeoGebra to create the graph.
The equation of the red line in slope intercept form (y = mx+b) is 
m = -3/5 is the slope
b = 4 is the y intercept

You can put this solution on YOUR website! The given is all you need to know. Plot point (0,4). Use slope to find any other points. Draw line through the points. Done. Graphed.
