The slope of the line is [tex]m=0[/tex]
Explanation:
Given that the line contains the points (-1,9) and (9,9)
We need to determine the slope of the line.
Slope:
The slope of the line can be determined using the formula,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The slope of the line can be determined by substituting the points (-1,9) and (9,9) in the above formula.
Thus, substituting the values, we have;
[tex]m=\frac{9-9}{9+1}[/tex]
Simplifying, we get;
[tex]m=\frac{0}{10}[/tex]
[tex]m=0[/tex]
Thus, the slope of the line is [tex]m=0[/tex]
