Question

introduction to slope - item 32605
use the coordinates of the plotted points to complete the calculation below.
pay attention to negative signs.
the slope of this line is
(1,4)
(3,2)

Explanation:

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 points

Points are \( A(1, 4) \) and \( B(3, 2) \), so \( x_1 = 1, y_1 = 4, x_2 = 3, y_2 = 2 \).

Step3: Substitute into formula

\( m=\frac{2 - 4}{3 - 1}=\frac{-2}{2}=-1 \).

Answer:

\(-1\)
