Answer.
If you want to graph the equation manually, you need to find our points.
For that give some arbitrary values for x and then find the corresponding values of f(x)
When , x = 0, then f(x) = -2(0) + 4 = 0 + 4 = 4
When , x = 1, then f(x) = -2(1) + 4 = -2 + 4 = 2
When , x = 2, then f(x) = -2(2) + 4 = -4 + 4 = 0
When , x = 3, then f(x) = -2(3) + 4 = -6 + 4 = -2
When , x = -1, then f(x) = -2(-1) + 4 = 2 + 4 = 6
When , x = -2, then f(x) = -2(-2) + 4 = 4 + 4 = 8
and so on....
now plot these values in a graph paper...
The the graph will come like this...
Here you can see that the solution of this equation is x = 
and y =
Hope you found the explanation useful.
