Question

find the slope of the line that passes through the pair of points. (5, -4), (9, -4)

Explanation:

Step1: Recall slope formula

La fórmula de la pendiente entre dos puntos $(x_1,y_1)$ y $(x_2,y_2)$ es $m=\frac{y_2-y_1}{x_2-x_1}$

Step2: Assign values to variables

Sea $(x_1,y_1)=(5,-4)$ y $(x_2,y_2)=(9,-4)$. Sustituimos en la fórmula:
$m=\frac{-4-(-4)}{9-5}$

Step3: Simplify the expression

$m=\frac{-4+4}{4}=\frac{0}{4}=0$

Answer:

$0$
