    That would be the perpendicular distance so you must first find the equation of the perpendicular through( 9,-7) that has slope 3.

    If memory serves, \(\huge \frac{ 2(9)+6(-7)-3 } { \pm \sqrt{2^2+6^2 } }\)

    Can you find the equation of a line whose slope is 3 and contains the point (9,-7)?

    THe formula for this, i think: \[\large \frac{ax_{1}+by_{1}+c}{\sqrt{a^{2}+b^{2}}} \]

    The proof requires representing the lines in normal form and then finding the perpendicular distances.

    Mimi, your formula is close but not apt, it should be Either, \[ \large \pm\frac{ax_{1}+by_{1}+c}{\sqrt{a^{2}+b^{2}}} \] or \[ \large \frac{|ax_{1}+by_{1}+c|}{\sqrt{a^{2}+b^{2}}} \] Recall, Euclidean distance cannot be negative :)

    Why should I answer you? Will I get anything? What is the purpose of anything in life? Life is as meaningless itself as this discussion :P
