im actually around that right now! are you in algebra 1-2?
anyways, the way i learned it is to put all of this into a x and y chart, or in this case a x and f(x) chart. i'll just give you the set up for it incase you dont know it yet. also, in my class for linear lines we only put 3 numbers but you can do more in the x side
the f(x) side is where you put the answer for the equations
| x | f(x) | |
| -2 | f(-2) = 1/2(-2) + 1 | |
| 0 | f(0) = 1/2(-1) + 1 | |
| 2 | f(2) = 1/2(2) + 1 |
after you finish finding the answers, you can graph them by simply putting the x and f(x) numbers together in parantheses ( , ) for example x was 9 and the answer to the equation was 11 so you put them together like so: (9,11)
after that just see if (2,2) is on the line! i hope this helps
