Since this is a linear equation, (you can tell because there aren't any exponents) you technically only need to find two points to determine the line.
Anyways, here is how we can find points.
1. Choose a value to use for x.
2. Plug this into the eqn.
3. Solve for y.
4. Plot this point (x, y).
Let's try x = 0.
2y = 5(0) + 11
2y = 11
y = 5.5
Let's try x = 1.
2y = 5(1) + 11
2y = 5 + 11
2y = 16
y = 8
Let's try x = 2.
2y = 5(2) + 11
2y = 10 + 11
2y = 21
y = 10.5
Here are our three points: (0, 5.5), (1, 8), and (2, 10.5).
Plot these on a graph and just connect them using a ruler.
