Answer:
Step-by-step explanation:
4) (-2,3) ; (-1,-2)
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-2-3}{-1-[-2]}\\\\=\frac{-5}{-1+2}\\\\=\frac{-5}{1}\\\\=-5[/tex]
5) line is parallel to x-axis. So, slope= 0
6) (1,1) ; (-2, -1)
[tex]Slope=\frac{-1-1}{-2-1}\\\\=\frac{-2}{-3}\\\\=\frac{2}{3}[/tex]
