Answer:
slope=2, therefore the line rises
Step-by-step explanation:
Use the formula to find the slope of a segment through two points [tex](x_1, y_1)[/tex] and [tex](x_1, y_1)[/tex] on the plane:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
we can name [tex](x_1, y_1)[/tex] = (8,6)
and [tex](x_2, y_2)[/tex] = (9,8)
Therefore, the slope becomes: [tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{8-6}{9-8}=\frac{2}{1} =2[/tex]
This is therefore a positive slope, which belongs to a line that rises 2 units every one unit run.
