<PRE><B>Question 1125456</B>
The equation of line L is ax + by = c
:
I assume a, b, c are real numbers
:
solve for y
:
y = (-ax/b) +(c/b)
:
slope of line L is -a/b and its y-intercept is c/b
:
the x-intercept c/a
:
the slope of the line perpendicular to L is b/a, since the y-intercept for this line is 0, we have
:
y = bx/a
