I don't speak the language; I'm not even sure what language that is. I went to Indonesia in 1991 but all I can say now is "saya mau beli mango."
But math is math. It says "graf"; this is probably making a table to help draw the graph.
It looks like the curve we're trying to graph is
[tex]x - y = 2[/tex]
That's
[tex]y = x - 2[/tex]
That's a fairly straightforward table to make; unfortunately our first entry isn't consistent with the above equation. I'll assume the equation is correct and make a vertical table; that's easier to type:
x y (x,y)
0 -2 (0,-2)
1 -1 (1,-1)
2 0 (2,0)
3 1 (3,1)
4 2 (4,2)
5 3 (5,3)
