Answer:
Undefined
Step-by-step explanation:
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.
