Use the coordinates of the plotted points to complete the calculation below. Pay attention to negative signs
Slope between two points
[tex](x_{1},y_{1}) \text{and},(x_{2},y_{2}) \text{is equal to}\\\\\text{and}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{1-2}{4-2}\\\\=\frac{-1}{2}[/tex]
Option D
[tex]\frac{-1}{2}[/tex]
