Line L passes through point (2, -5) and is perpendicular to the line with equation y = 7. Determine the equation of line L.
A) x = 2
B) x = 7
C) x = -5
D) y = -5
E) y = 2
This is easy
If the line is perpendicular to y = 7 then the equation we are looking for is
x = (the x coordinate of the given point) ...so......
x = 2
