Two lines are perpendicular if the product of their slopes is -1
and
Two lines are parallel if their slopes are equal
These should be stated in your book or should be taught by your instructor.
and the equation of a line passing through a point is given by:
.............................(I)
Now use this above formula to find the equation of the line passing through (2,3).
------------------------------------------------------------------------------------
for the line ., find the slope of this line by re-writing the equation in the form of ; where m is the slope.
so you have :
so the slope of this line is . since the two lines are parallel, the slope of the other line should also be
so you have the point(2,3) and the slope m = -3/2. plug these in equation (I) to find the equation of the line.
