Question

1. $y = 7 - 4x$

$x$	$y$
1
2
3
4

(and a coordinate grid graph)

Explanation:

Step1: Substitute \( x = 0 \) into \( y = 7 - 4x \)

\( y = 7 - 4\times0 = 7 \)

Step2: Substitute \( x = 1 \) into \( y = 7 - 4x \)

\( y = 7 - 4\times1 = 3 \)

Step3: Substitute \( x = 2 \) into \( y = 7 - 4x \)

\( y = 7 - 4\times2 = -1 \)

Step4: Substitute \( x = 3 \) into \( y = 7 - 4x \)

\( y = 7 - 4\times3 = -5 \)

Step5: Substitute \( x = 4 \) into \( y = 7 - 4x \)

\( y = 7 - 4\times4 = -9 \)

Answer:

When \( x = 0 \), \( y = 7 \); when \( x = 1 \), \( y = 3 \); when \( x = 2 \), \( y = -1 \); when \( x = 3 \), \( y = -5 \); when \( x = 4 \), \( y = -9 \)

The completed table is:

\( x \)	\( y \)
1	3
2	-1
3	-5
4	-9
