Step1: Recall slope formula
The slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is \( m=\frac{y_2 - y_1}{x_2 - x_1} \).
Step2: Identify coordinates
The two points are \((-3, 3)\) and \((-3, 1)\). So \( x_1=-3, y_1 = 3, x_2=-3, y_2 = 1 \).
Step3: Substitute into formula
Substitute into the slope formula: \( m=\frac{1 - 3}{-3 - (-3)}=\frac{-2}{0} \). Division by zero is undefined, and a vertical line (where \( x \)-coordinates are equal) has an undefined slope.
