This means that the y-intercept is at

Start the graph by marking that point.
the slope is

From

, count UP 5 units and 3 to the LEFT, mark a point.
Again, count UP 5 units and 3 to the LEFT, mark a point.
From
6

3
, count DOWN 5 units and 3 to the RIGHT, mark a point.
Again, count DOWN 5 units and 3 to the RIGHT, mark a point.
This will give you 5 points which you can use to draw the straight line. Remember to write the equation on the line.
graph{y= -5/3 x+ 19/3 [-11.71, 8.29, 3.1, 13.1]}
