This graph shows a proportional relationship. What is the constant of proportionality?

Enter your answer as a decimal in the box.

The constant of proportionality is 0.3

Step-by-step explanation:

» The graph shows a direct proportiinality.

» Therefore, input the constant;

» When x is 5, y is 1.5:

0.3

Step-by-step explanation:

On a graph, proportional relationships are straight lines that extend through the origin.  

Slope of a graph = constant of proportionality of the equation

Let (5, 1.5) =

Let (20, 6) =

Formula of a slope:

So as the slope = 0.3, the constant of proportionality = 0.3

you need to show us the graph.

step-by-step explanation:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
