bresenhem's line drawing algorithm

how to find pixels required for generating a line from(0,0) to (10,5)

initial calculation-

x=0

y=0

Δx=x2-x1 = 10-0= 10

Δy=y2-y1, 5-0, 5→2Δy=10

m= Δy/Δx = 5/10 = 1/2

2Δy-2Δx = 10-20 = -10

first plot(0,0)

now incrementing through main loop yields next plots. now how to find next plot. i am confuse here
