Question

#3 Determine the constant of proportionality of the graph 4

Answer 1

20

Step-by-step explanation

Step 1

choose two points from the line

`\begin{gathered} P1(0,0) \\ \text{and} \\ P2(2,40) \end{gathered}`

Step 2

the constant of proportionality is given by

`\begin{gathered} C=(f(b)-f(a))/(b-a) \\ C=(y_(p2)-y_(p1))/(x_(p2)-x_(p1)) \\ \text{replace} \\ C=(40-0)/(2-0) \\ C=(40)/(2) \\ C=20 \end{gathered}`

so, the answer is 20
