The table represents a linear function.
\begin{tabular}{|c|c|}
\hline
[tex]$x$[/tex] & [tex]$y$[/tex] \\
\hline
-2 & 8 \\
\hline
-1 & 2 \\
\hline
0 & -4 \\
\hline
1 & -10 \\
\hline
2 & -16 \\
\hline
\end{tabular}

What is the slope of the function?

A. [tex]$-6$[/tex]
B. [tex]$-4$[/tex]
C. [tex]$4$[/tex]



Answer :

To determine the slope of the linear function represented by the given points, follow these steps:

1. Select any two consecutive data points from the table to use for calculations. In this case, let's use the points [tex]\((-2, 8)\)[/tex] and [tex]\((-1, 2)\)[/tex].

2. Calculate the change in [tex]\( y \)[/tex] (often referred to as [tex]\(\Delta y\)[/tex] or "delta y") between these two points:
[tex]\[ \Delta y = y_2 - y_1 = 2 - 8 = -6 \][/tex]

3. Calculate the change in [tex]\( x \)[/tex] (often referred to as [tex]\(\Delta x\)[/tex] or "delta x") between these two points:
[tex]\[ \Delta x = x_2 - x_1 = -1 - (-2) = -1 + 2 = 1 \][/tex]

4. Finally, determine the slope ([tex]\(m\)[/tex]) of the function using the formula:
[tex]\[ m = \frac{\Delta y}{\Delta x} = \frac{-6}{1} = -6 \][/tex]

Based on these calculations, the slope (m) of the linear function is [tex]\(-6\)[/tex].

Therefore, the answer is:
[tex]\[ -6 \][/tex]
