Keep in mind:
constant of proportionality = the slope
Step-by-Step Step-by-step explanation:
We can see that the point is at (4, 6). In order to find the slope, we need to find a different point that intercepts a whole number point on the graph.
We have two valid points; (2, 3) and (6, 9). One way to find the slope is to subtract y-coordinate 1 (6) and y-coordinate 2 (3 or 9).
Then, subtract x-coordinate 1 (4) and x-coordinate 2 (2 or 6).
![(6 - 3)/(4 - 2) = (3)/(2)](https://img.qammunity.org/2023/formulas/mathematics/middle-school/nb94ww8s29uyuh93kubxkfrizq18h5fd1v.png)
OR
![(6 - 9)/(4 - 6) = ( - 3)/( - 2) = (3)/(2)](https://img.qammunity.org/2023/formulas/mathematics/middle-school/giao8dub2pq9zmg7tj77tf44hte4lkspgl.png)
