Hope this helped :)
Answer:
Area of rectangle = l x b
18 = l x b
Factors of 18 =
1 x 18 = 18
2 x 9 = 18
3 x 6 = 18
So each of the sides can be either 1cm and 18 cm, 2cm and 9cm and 3cm and 6cm.
A vertical line can only pass through the x axsis not the y unless it was at 0 then it would pass through all the y points. A diagonal line can pass through (-5,1) but not a vertical choose x=-5 if you want it to be a vertical line going through (-5,0)
