 Click here to see ALL problems on Functions Question 94992: Ok, My son came home from school today with Math homework. He is in Algebra 1 and they have requested he have a TI-83. I intend to buy this for him but I haven't yet and he has homework tonight. The teacher only explained how to do the problem on the calulator not on paper. I know it can be done on paper but I really do not remember how to do it. I looked in his math book and the book only goes to Chapter 12 and the worksheet is for Chapter 13. I can't figure out how to solve these problems and I'm hoping for some help. The question reads as follows: Find the solution set for each equation, given the replacement set. One of the problems(not one he has to do) read as follows: y=4x=1; {(2,-1), (1,5), (9,2), (0,1)}. If you could explain how to do this problem I'm sure we can do the problems he has to turn in for homework. Thank you. Answer by stanbon(57214)   (Show Source): You can put this solution on YOUR website!Find the solution set for each equation, given the replacement set. One of the problems(not one he has to do) read as follows: y=4x+1; {(2,-1), (1,5), (9,2), (0,1)}. -------------- Each of the pairs gives you values for x and for y . You are to take one pair at a time and insert them into the equation to see if you get a true result, as follows: Looking at (2,-1) you would get: -1=4*2+1 -1=8+1 That is wrong ------------------- Looking at (1,5) you would get: 5=4*1+1 5=4+1 5=5 That is right so that pair is a solution for the equation ------------------------------------------ Looking at (9,2) you would get: 2=4*9+1 2=36+1 2=37 Not a solution for the equation. ---------------- Try the other pairs and see what you get; good luck. ====================== cheers, Stan H.
