The boundary line is the equation y = (2/3)x + 1 which can be found through the slope formula to get m = 2/3. Then you use one of the two points on the line to find b = 1.
The equal sign in y = (2/3)x + 1 changes to a "greater than" sign to indicate two things A) The shaded region is above the boundary line B) The boundary line itself is a dashed line to indicate "no solution points on this line"
