Find the equation of the line passing through (0, 0) with slope m.
Advertisements
Solution
The equation of the line passing through (x1, y1) with slope m is given by \[y - y_1 = m\left( x - x_1 \right)\]
So, the equation of the line passing through (0, 0) with slope m is
\[y - 0 = m\left( x - 0 \right) \]
\[ \Rightarrow y = mx\]
