Answer:
2
Step-by-step explanation:
we know the line goes through the origin, so we have point (0,0). next, find another point the line goes through. for example, point (2,4)
the slope formula for points (x1, y1) and (x2, y2) is (y2 - y1) / (x2 - x1). plug in the 2 points to get (4-0)/(2-0) = 4/2 = 2
