Question

What is the slope of the line that passes through the points (6, -2) and (12,-2)?

Answer 1

Answer:

Zero

Step-by-step explanation:

The formula to calculate slope is :

$m=\frac{y_2-y_1}{x_2-x_1}$

We have two points ( 6 , -2 ) and ( 12 , -2 )

so now,

$m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-2-(-2)}{12-6} \\\\m=\frac{-2+2}{6}\\\\m=0/6\\m=0$

This means the line is parallel to x-axis , whenever the slope is zero the line is always parallel to x-axis and when the slope is undefined the line is always parallel to y-axis.
