Y=X+50 AS X INCREASES BY 1 THEN Y INCREASES BY 1
PROOF.
LET X=10 Y=10+50=60 NOW INCREASE X BY 1 (X+1)=11 Y=11+50=61
------------------------------------------------------------------------
Y=-5X+10 AS X INCREASES BY 1 Y DECREASES BY 5.
PROOF
LET X=8 Y=-5*8+10=-40+10=-30 NOW INCREASE X BY 1 (8+1)=9 Y=-5*9+10=-45+10=-35
