The missing value for [tex]x=-1[/tex] is [tex]y=6[/tex]
Explanation:
It is given that the equation for the table is [tex]y=2-4x[/tex]
The table has 2 column with 5 rows.
Thus, we have,
x    y
-2 Â Â Â 10
-1 Â Â Â ---
0 Â Â Â Â 2
1 Â Â Â Â -2
2 Â Â Â -6
We need to determine the value of y when [tex]x=-1[/tex]
The value of y can be determined by substituting [tex]x=-1[/tex] in the equation [tex]y=2-4x[/tex]
Thus, we have,
[tex]y=2-4(-1)[/tex]
Multiplying the term within the bracket, we have,
[tex]y=2+4[/tex]
Adding the terms, we have,
[tex]y=6[/tex]
Thus, the value of y when [tex]x=-1[/tex] is 6.
Hence, the missing value for [tex]x=-1[/tex] is [tex]y=6[/tex]
The missing value for y is 6 at x = -1.
The solution to the table is
X Â Â Â Â Â Â Y
-2 Â Â Â Â Â Â 10
-1 Â Â Â Â Â Â Â 6
0 Â Â Â Â Â Â Â 2
1 Â Â Â Â Â Â Â -2
2 Â Â Â Â Â Â -6
Given to us:
X Â Â Â Â Â Â Y
-2 Â Â Â Â Â Â 10
-1 Â Â Â Â Â Â Â __
0 Â Â Â Â Â Â Â 2
1 Â Â Â Â Â Â Â -2
2 Â Â Â Â Â Â -6
Equation: Â y = 2 - 4x
The value of y can be determined by substituting the values in the equation, put the value of x in the equation given in the question,
y = 2 - 4x
Using BODMAS, therefore solving the term within the bracket,
y = 2 - 4(-1) Â
Multiplying the terms,
y = 2 + 4
Further after addition, we get,
y = 6
Hence, the missing value for y is 6 at x = -1.
