To determine the relationship between [tex]\( x \)[/tex] and [tex]\( y \)[/tex] in the given table, we need to find the linear equation in the form:
[tex]\[ y = mx + b \][/tex]
where [tex]\( m \)[/tex] is the slope and [tex]\( b \)[/tex] is the y-intercept.
Given data points:
[tex]\[ (0, 1) \\ (1, -1) \\ (2, -3) \\ (3, -5) \\ (4, -7) \\ (5, -9) \][/tex]
### Step 1: Calculate the Slope (m)
The slope [tex]\( m \)[/tex] of a line passing through two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex] can be found using the formula:
[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]
Using the first two points [tex]\((0, 1)\)[/tex] and [tex]\((1, -1)\)[/tex]:
[tex]\[ m = \frac{-1 - 1}{1 - 0} \][/tex]
[tex]\[ m = \frac{-2}{1} \][/tex]
[tex]\[ m = -2 \][/tex]
### Step 2: Calculate the Y-Intercept (b)
The y-intercept [tex]\( b \)[/tex] can be found using the point-slope form of the equation:
[tex]\[ y = mx + b \][/tex]
Using the point [tex]\((0, 1)\)[/tex]:
[tex]\[ 1 = (-2)(0) + b \][/tex]
[tex]\[ 1 = b \][/tex]
Therefore, the y-intercept [tex]\( b \)[/tex] is [tex]\( 1 \)[/tex].
### Step 3: Form the Equation
Now that we have the slope [tex]\( m = -2 \)[/tex] and the y-intercept [tex]\( b = 1 \)[/tex], we can write the equation:
[tex]\[ y = -2x + 1 \][/tex]
So, the completed table with the equation is:
[tex]\[ \begin{tabular}{|c|c|c|} \hline x & y & y = mx + b \\ \hline 0 & 1 & \\ \hline 1 & -1 & \( y = -2x + 1 \) \\ \hline 2 & -3 & \( y = -2 \cdot x + 1 \) \\ \hline 3 & -5 & \\ \hline 4 & -7 & \\ \hline 5 & -9 & \\ \hline \end{tabular} \][/tex]
Thus, the linear equation describing the relationship between [tex]\( x \)[/tex] and [tex]\( y \)[/tex] is:
[tex]\[ y = -2x + 1 \][/tex]
[tex]\[ y = mx + b \][/tex]
where [tex]\( m \)[/tex] is the slope and [tex]\( b \)[/tex] is the y-intercept.
Given data points:
[tex]\[ (0, 1) \\ (1, -1) \\ (2, -3) \\ (3, -5) \\ (4, -7) \\ (5, -9) \][/tex]
### Step 1: Calculate the Slope (m)
The slope [tex]\( m \)[/tex] of a line passing through two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex] can be found using the formula:
[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]
Using the first two points [tex]\((0, 1)\)[/tex] and [tex]\((1, -1)\)[/tex]:
[tex]\[ m = \frac{-1 - 1}{1 - 0} \][/tex]
[tex]\[ m = \frac{-2}{1} \][/tex]
[tex]\[ m = -2 \][/tex]
### Step 2: Calculate the Y-Intercept (b)
The y-intercept [tex]\( b \)[/tex] can be found using the point-slope form of the equation:
[tex]\[ y = mx + b \][/tex]
Using the point [tex]\((0, 1)\)[/tex]:
[tex]\[ 1 = (-2)(0) + b \][/tex]
[tex]\[ 1 = b \][/tex]
Therefore, the y-intercept [tex]\( b \)[/tex] is [tex]\( 1 \)[/tex].
### Step 3: Form the Equation
Now that we have the slope [tex]\( m = -2 \)[/tex] and the y-intercept [tex]\( b = 1 \)[/tex], we can write the equation:
[tex]\[ y = -2x + 1 \][/tex]
So, the completed table with the equation is:
[tex]\[ \begin{tabular}{|c|c|c|} \hline x & y & y = mx + b \\ \hline 0 & 1 & \\ \hline 1 & -1 & \( y = -2x + 1 \) \\ \hline 2 & -3 & \( y = -2 \cdot x + 1 \) \\ \hline 3 & -5 & \\ \hline 4 & -7 & \\ \hline 5 & -9 & \\ \hline \end{tabular} \][/tex]
Thus, the linear equation describing the relationship between [tex]\( x \)[/tex] and [tex]\( y \)[/tex] is:
[tex]\[ y = -2x + 1 \][/tex]
