Question

For each function shown:

Answer 1

#1: y= 0.5+3 x
which means that x= y/3 - 0.5

#2: y= 3(0.5) x
which means that y= 1.5 x
that means x = y/1.5

Hope it can help

Answer 2

Function #1:  As x increases y gradually increases by adding 3.

Function #2:  As x increases y gradually decreases by dividing by 2.
