The slope of the line PQ is 0
The slope of the line MN is ∞
The line PQ is a horizontal line while the line MN is a vertical line
The formula for calculating the slope of the line is expressed as:
[tex]m = \frac{y_2-y_1}{x_2-x_1} \\[/tex]
For the line PQ with the coordinates (-8, 2) and (4, 2)
[tex]m_{PQ} = \frac{2-2}{4-(-8)} \\m_{PQ} = \frac{0}{12} \\m_{PQ} = 0[/tex]
Similarly for the line MN with coordinates
[tex]m_{MN} = \frac{-8-6}{8-8)} \\m_{MN} = \frac{-14}{0} \\m_{MN} = \infty[/tex]
The line PQ is a horizontal line while the line MN is a vertical line
