Question 28919: the question states, write an equation for the line that is perpendicular to the givin line and that passes through the givin line.
how would i do
y=2x+7;(0,0)?

You can put this solution on YOUR website!
The slope of the given line is m=2
Therefore the slope of a line perpendicular to it will be m=-1/2
Since the line passes through (0,0), the y-intercept is "0".
Therefore the equation of the line you want is y=(-1/2)x+0 or
simply, y=-(1/2)x
