Question

1. $y = 4 - x$

$x$	$y$
$-1$
$0$
$5$
$9$

1. $y = $

Explanation:

Step1: Substitute \( x = -4 \) into \( y = 4 - x \)

\( y = 4 - (-4) = 4 + 4 = 8 \)

Step2: Substitute \( x = -1 \) into \( y = 4 - x \)

\( y = 4 - (-1) = 4 + 1 = 5 \)

Step3: Substitute \( x = 0 \) into \( y = 4 - x \)

\( y = 4 - 0 = 4 \)

Step4: Substitute \( x = 5 \) into \( y = 4 - x \)

\( y = 4 - 5 = -1 \)

Step5: Substitute \( x = 9 \) into \( y = 4 - x \)

\( y = 4 - 9 = -5 \)

Answer:

When \( x = -4 \), \( y = 8 \); when \( x = -1 \), \( y = 5 \); when \( x = 0 \), \( y = 4 \); when \( x = 5 \), \( y = -1 \); when \( x = 9 \), \( y = -5 \)

Filling the table:

\( x \)	\( y \)
\( -1 \)	\( 5 \)
\( 0 \)	\( 4 \)
\( 5 \)	\( -1 \)
\( 9 \)	\( -5 \)
