Ok we can writue the equation of the second point and replace x=18 and the solution must be -8, if isnt the solution the line doesnt pass through the point
calculate the parallel line to second point
the slope is -2/3
we replace on the general equation of the line and replace the point C(3,2)

and solve for b

the parallel line on the second point is

Third point
replace x=18

so this graph has the point (18,-8), then the line pass through E
