Answer:
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= [tex]\frac{y}{x}[/tex]
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 .
