Question

y = 2x - 4
x | y
-1 |
0 |
1 |
2 |

Explanation:

Step1: Substitute \( x = -1 \) into \( y = 2x - 4 \)

\( y = 2\times(-1) - 4 = -2 - 4 = -6 \)

Step2: Substitute \( x = 0 \) into \( y = 2x - 4 \)

\( y = 2\times0 - 4 = 0 - 4 = -4 \)

Step3: Substitute \( x = 1 \) into \( y = 2x - 4 \)

\( y = 2\times1 - 4 = 2 - 4 = -2 \)

Step4: Substitute \( x = 2 \) into \( y = 2x - 4 \)

\( y = 2\times2 - 4 = 4 - 4 = 0 \)

Answer:

When \( x = -1 \), \( y = -6 \); when \( x = 0 \), \( y = -4 \); when \( x = 1 \), \( y = -2 \); when \( x = 2 \), \( y = 0 \)

Filling the table:

\( x \)	\( y \)
0	-4
1	-2
2	0
