Question

Find the slope and the equation of the line passing through the points: (a, b) and ( - a, b)

Philoid · Accepted Answer

The slope of the equation can be calculated using

m = 0 (Horizontal line)

Now using two point form of the equation of a line

y - b = 0(x - a)

y = b

So, required equation of line is y = b.
