What is the slope of the graph?

What is b if the y-intercept is (0, b) ?
We would shift the graph up ____ units to make this proportional.
The slope triangles show that ___/9 = 4/3 .

Without more specific information or a given graph, it is not possible to determine the slope of the graph or the value of b. Similarly, without the information about the number of units the graph would need to be shifted up, it is not possible to fill in that blank. Additionally, the statement "The slope triangles show that ___/9 = 4/3" is also incomplete and cannot be answered without more information.
