I can help you because I know how to convert fractions to mixed numbers, but what is the question exactly?
Answer:
2
Step-by-step explanation:
If we look at the graph this is an increasing graph where y increases with respect to x so in other words we can say that y is directly proportional to x.
![y\ \alpha\ x\\](https://tex.z-dn.net/?f=y%5C%20%5Calpha%5C%20x%5C%5C)
and when we remove the proportionality sign we replace it with an equal to sign and a constant. So it becomes ,
![y = kx\\](https://tex.z-dn.net/?f=y%20%3D%20kx%5C%5C)
now to find the Constant of proportionality which is k we can use any ordered pair(coordinate/point) from the graph,
Lets take ( 2 , 4) where 2 represents the value of x on the x-axis and 4 represents the value of y on the y-axis so now,
![y=kx\\(4)=k(2)\\4=2k\\4/2=k\\k=2\\](https://tex.z-dn.net/?f=y%3Dkx%5C%5C%284%29%3Dk%282%29%5C%5C4%3D2k%5C%5C4%2F2%3Dk%5C%5Ck%3D2%5C%5C)
so the constant of proportionality is 2
The answer is D. 4x7+5=33 8x7+5=61. Hope it helps
