Given the coordinates of the points passing through a line:

[tex](0,6)\text{ and (-8,6)}[/tex]

Let's name the given coordinates:

x1, y1 = -8,6

x2, y2 = 0,6

In determining the slope (m), we will be using this formula:

[tex]\text{ m = }\frac{y_2-y_1}{x_2-x_1}[/tex]

Let's plug in the coordinates in the formula to be able to get the slope (m).

[tex]\text{ m = }\frac{y_2-y_1}{x_2-x_1}[/tex][tex]\text{ m = }\frac{6-6_{}}{0_{}-(-8)_{}}=\frac{6\text{ - 6}}{0\text{ + 8}}[/tex][tex]\text{ m = }\frac{0}{8}[/tex][tex]\text{ m = 0}[/tex]

Therefore, the slope of the line (m) = 0. The line is a horizontal line and has no slope.

The same thing works at question 17 at x1,y1 = -5,6 and x2,y2 = -5,10.
