Slope = -13
Explanations:The slope of a line passing through two points with coordinates (x₁ , y₁ ) and (x₂ y₂) is calculated using the formula:
[tex]\text{Slope = }\frac{y_2-y_1}{x_2-x_1}[/tex]Since the points are (6, 6) and (7, -7):
x₁ = 6, y₁ = 6, x₂ = 7, y₂ = -7
Substituting these into the formula:
[tex]\begin{gathered} \text{Slope = }\frac{-7-6}{7-6} \\ \text{Slope = }\frac{-13}{1} \\ \text{Slope = -13} \end{gathered}[/tex]
