graphing linear equations
vectored instruction
graph the
equation by filling
in the chart.
equation:
y = 9 - x
x | y
0 | 9
1 | 8
2 | 7
3 | ?
4 |

Explanation:

Step1: Substitute x = 3 into the equation

We have the equation \( y = 9 - x \). Substitute \( x = 3 \) into it.
\( y = 9 - 3 \)

Step2: Calculate the value of y

Simplify the right - hand side of the equation: \( 9 - 3=6 \)

Step3: Substitute x = 4 into the equation

Substitute \( x = 4 \) into \( y = 9 - x \), we get \( y = 9 - 4 \)

Step4: Calculate the value of y

Simplify the right - hand side of the equation: \( 9 - 4 = 5 \)

Answer:

When \( x = 3 \), \( y = 6 \); when \( x = 4 \), \( y = 5 \)

So the completed table is:

X	Y
1	8
2	7
3	6
4	5
