SOLUTION: I am trying graph functions and I get a good graph but it doesn't match any that I am supposed to "pick from" The first one is f(x)= -2x+4 I used -2 as x and came out with 8

Question 633443: I am trying graph functions and I get a good graph but it doesn't match any that I am supposed to "pick from"
The first one is f(x)= -2x+4
I used -2 as x and came out with 8 for Y also (-1,6), (0,4), (1,2) and (2,0)I made a chart but since it doesn't match with the answers I am stumped. What is the difference between graphing equations and graphing functions?

I am trying graph functions and I get a good graph but it doesn't match any that I am supposed to "pick from"
The first one is f(x)= -2x+4
I used -2 as x and came out with 8 for Y also (-1,6), (0,4), (1,2) and (2,0)-------
If x = -2, y = -2*-2+4 = 8
If x = -1, y = -2*-1+4 = 6
If x = 0, y = -2*0+4 = 4
If x = 1, y = -2*1+4 = 2
If x = 2, y = -2*2+4 = 0

Your points are correct. Plot them and draw
