Question

1. (19, 3), (20, 3)

Explanation:

Step1: Recall slope formula

The slope \( m \) between two points \( (x_1, y_1) \) and \( (x_2, y_2) \) is given by \( m=\frac{y_2 - y_1}{x_2 - x_1} \).

Step2: Identify coordinates

Here, \( x_1 = 19 \), \( y_1 = 3 \), \( x_2 = 20 \), \( y_2 = 3 \).

Step3: Substitute into formula

Substitute the values into the slope formula: \( m=\frac{3 - 3}{20 - 19} \).

Step4: Simplify numerator and denominator

The numerator \( 3 - 3 = 0 \) and the denominator \( 20 - 19 = 1 \). So \( m=\frac{0}{1}=0 \).

Answer:

The slope between the two points is \( 0 \).
