What steps are needed to apply another point on this graph of equivalent ratios

OPTION B

Step-by-step explanation:

Note that the graph represents the function f(x) = 2x.

Because the points are: .

So, to mark the next point, take any two points on the graph, say .

From (1, 2) to reach (2, 4) it has shifted one place  right. Because the x - co ordinate has increased by 1.

And then moved by 2 units because the y co ordinate increases by 2 for every one unit increase in x - co ordinate.

So, the steps would be as follows:

1. Start at any point.

2. Move up one space

3. Move right two spaces.

Hence, Option B is the answer.
