to graph the line, plot the point (-5,-2)
Now, since the slope is 1/2, that means that y increase by 1 when x increases by 2. So, starting at (-5,-2), move right 2 and up 1 and plot that point : (-3,-1).
Draw the line through those two points.
the slope of 5x+5y=3 is -1
The slope of 2x-4y=4 is 1/2. So is the slope of all lines parallel to it. The slope of all perpendiculars to it is -2.
