the equation of line:
where is a slope and is y-intercept
if passing through (,) and (,), use these points to find and
first find

Solved by pluggable solver: Finding the slope

Slope of the line through the points (1, 2) and (1, -2)

Since you CANNOT divide by 0, this means that the slope of the line is undefined.

Answer: The slope of the line is undefined.

since the slope of a line is , your line is a line

Find the equation of line passing through (1,2) (1,-2)

As the x-coordinates repeat, or there're more than 1 y-values that're MAPPED to one (1) x-value,
the line has an UNDEFINED SLOPE, is vertical, is PARALLEL to the y-axis, and is therefore:
That's it!! Nothing COMPLEX and/or CONFUSING!
