What is the equation for the line through (-19,16) with undefined slope?

Question

What is the equation for the line through (-19,16) with undefined slope?

Answer 1

An undefined slope is one where

m = (y₂-y₁)/0

because the x coordinates don't change.

Example: slope of the line through

(-7,2), (-7, 5) = 3/0 which is

undefined.  The line would be:

x = -7

 

Undefined slope and through (-19, 16)

is x = -19

Answer 2

If the slope is undefined it means the slope is infinite and the line is therefore parallel to the y axis

 

If it passes through (-19, 16) the equation is: x = -19
