The slope of the line that passes through (10,8) and (1,9) is -1/9
The formula for calculating the slope of a line is expressed according to the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
Given the coordinate points (10,8) and (1,9), the slope is expressed as:
[tex]m=\frac{9-8}{1-10}\\m=\frac{1}{-9}\\m=-\frac{1}{9}[/tex]
Hence the slope of the line that passes through (10,8) and (1,9) is -1/9
