Hi Jake;
If there was no equal sign, you will use a dotted line.
Because of the equal sign, you will use a nondotted line.
y <= 4/9 x  3
We already know one point on the line. It is the yintercept, (0,3). We know this because the equation is in slopeintercept format...
y=mx+b
m is the slope, 4/9.
b is the yintercept.
Begin with the yintercept. Then, the slope will function as 4/9. You will move up, positively, 4 points on the yaxis, and then to the left, negatively, 9 points on the xaxis. Then extend the line. Then, you will shade the area to the left.
