Passing through (0, 0) with slope m.
Here x0=0, y0=0 and slope = m
Putting these values in y−y0=m(x−x0), we have
∴ y - 0 = m(x - 0) ⇒ y = mx.
Any line y = mx (where m is the slope) always passes through the point:
Consider a line passing through the points (0,0) and (2,2). Then the slope of this line is _____.
