What are the equations of the two parallel lines shown here?
(1) Point A has coordinates (0,2)
(2) Point B has coordinates (-3,0)
Why not C?
Using Point A and B, equation of line joining both points can be found, finally slope ( say m)
We know that line is perpendicular with those parallel lines. (So slope of these lines will be -1/m)
Using one Point A and slope (-1/m) we can derive equation
Like wise, Point B can be done.
Do we know that the line joining points A and B is perpendicular to these parallel lines??... The figure suggests so, however, there is no mention of that in the question statement.. We cannot determine that this line is perpendicular...
