The actual reduced ratio is 7:2
The line equation in slope-intercept form is y=mx+b
You have one line with a y-intercept at 1 and a slope of -3 -> y=-3x+1
and another with a y-intercept at -1 and a slope of 
-> 
The area marked is below the first line and above the second one -> replace = with < and >:
y<-3x+1
Which is the system of linear inequalities shown in the graph
Well you can set it up 26/100 and X/50 and cross multiply to get 100X=1300 and hen divide by 100 and you get 13 then you subtract 50 by 13 to get 37.
Apply Pythagoras:
length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)
