Determine whether the functions are inverses

Ok so for this question, you have to draw a graph to . i'm doing the numbers by 2. you plot the points (21,32) on the graph then after that plot the points by the slope. what i'm trying to say by that is: 1.5 as a fraction is 3/2. so you count from that point by going 3 numbers up (or squares if on a graph if it makes more sense) then count 2 squares to the right and you continue doing that after every point you make (if there's no space to go up the graph the n you can go down by just counting 3 down then counting 2 to the left)

i don't have graph paper on me so i can't really tell you the y-intercept because it might be not accurate (thats the number after the slope or "b" in the formula y=mx+b) how to find that is: when you follow the steps above you're going to hit the y-axis (vetical line) when you have an exact point hitting the y-axis (it should be right on that line ) then that's your number

equation: y=1.5x+ (insert y-axis number here)
the coordiantes of another point is on the line (u can pick any)

You will compose the  functions   (that is, plug x into one  function , plug that  function   into the  inverse function , and then simplify) and verify that you end up with just "x". here's what it looks like:   determine  algebraically  whether   f (x) = 3x – 2 and g(x) =  (x  +  2)/3  are  inverses   of each other.

The answer is the first one
