Answer:
that graph will feature an area delimited by a line of slope m passing through the origin (0,0).
Since m>0 the slope is positive, meaning the line goes up.
Since the equation is y > mx, the inequality sign being >, that means the area represented will be ABOVE the line drawn.
So it will for sure include ALL quadrant II (with -x and +y values) and NONE of the quadrant IV (with +x and -y values) since the line is passing through the origin (0,0).
