Question

find the slope of the line through the points (2,-4) and (3,-4). is the line horizontal, vertical, or neither

Answer 1

Answer:

The slope of the line is 0 and the line is horizontal

Step-by-step explanation:

Given coordinates;

                      (2,-4) and (3,-4)

Unknown:

Slope of the line  = ?

Solution:

The slope of a line is the rise divided by the run. Mathematically, it is expressed as;

    Slope  = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

x₁  = 2

x₂ = 3

y₁ = -4

y₂ = -4

 Insert the parameters and solve;

   Slope  = $\frac{-4-(-4)}{3-2}$   = 0

The slope of the line is 0 and the line is horizontal
