Question

1. $x + y = 9$

$x$	$y$

Explanation:

Step1: Rearrange for y

$y = 9 - x$

Step2: Pick x values, solve for y

Choose $x=0,1,2,3$:

• $x=0$: $y=9-0=9$
• $x=1$: $y=9-1=8$
• $x=2$: $y=9-2=7$
• $x=3$: $y=9-3=6$

Step3: Plot points on grid

Points: $(0,9), (1,8), (2,7), (3,6)$; draw line through them.

Answer:

Completed Table:

$x$	$y$
1	8
2	7
3	6

Graph Instructions:

Plot the points $(0,9)$, $(1,8)$, $(2,7)$, $(3,6)$ on the grid, then draw a straight line passing through all these points (extending it to cover the grid as needed).
