Answer:
infinite
Step-by-step explanation:
We need to find the slope of the line passing through the points (6,6) and (6, -7).
The slope of a line can be calculated as the formula as follows :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have,
x₁ = 6, y₁ = 6, x₂ = 6 and y₂ = -7
Put all the values,
[tex]m=\dfrac{-7-6}{6-6}\\\\m=\infty[/tex]
So, the slope of the line is equal to infinite.
