1.
y+=+-10x+%2B+110
=> x=2 => y=90
=> x=9 => y=-90%2B110=20

2.
y+=+-%281%2F2%29x+%2B+110
=> x=20 => y=100
=> x=40 => y=-20%2B110=90

4.
y+=+%281%2F10%29x+-+197
=> x=1990 => y=199-197=2...for some reason, on a graph shows 2.4
=> x=1996 => y=199.6-197=2.6...here too,on a graph shows 3 even it cannot be 3
