When x = 1 ; (1) - y = 1

ioda

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

$x - y = 2$

That's

$y = x - 2$

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)
