Graph a line that is parallel to the given line. Determine the slope of the given line and the one you graphed in simplest form. Click and drag on the graph to draw a line. Click and drag to plot a parallel line. The line will change colors when a parallel or perpendicular line is drawn accurately. 10 -6 3. 5 6 8 9 10 -8 -5 -4 -2 1 2. 4 -1 -10 -9 -7 -6 -7 -8
