Asap
what is the constant of proportionality for the graph
a. 0.5
b. 1
c. 2
d. 6

If the graph was on a clear grid then the accurate answer could be calculated from it but it is not clear

however the formula to solving the question is K=

whereby k is the constant

              x  is the x value of a coordinate on the graph

              y is the y value of the same coordinate on the graph

but if you were to estimate the coordinate then you are likely to get the coordinates (1,2) which will give you the answer of A)0.5

but then again it is not on a clear grid .

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
