Answer:
y = 2x
Explanation:
Since the line passes through the origin or (0,0), adding + 0 is irrelevant so we are just looking for slope.
Since there is a rise of 2 units every one unit, the slope or m = 2.
Since we know two points by observing the graph (0,0) and (3,6). m = y2-y1/x2-x1 = 6-0/3-0 = 6/3 = 2/1 = 2
