Don't repost because somebody will answer (probably)
we got some points normally it is like y=mx+b find m and x if we assume they are in a straight line m is slope and b is y intercept ok so we see the slope betwee (6,11) and (3,5) is 2 because slope between (x1,y1) and (x1,y1) is (y2-y1)/(x2-x1)
y=2x+b if we solve for b we get hmm 5=2(3)+b 5=6+b -1=b
y=2x-1
so double x and minus 1 to get y 10*2=20, 20-1=19
23=2x-1 24=2x 12=x
the missing points are 19 on right side and 12 on left rule is y=2x-1 or 2x-y=1
