Question

Find the constant of proportionality AND write an equation to represent the relationship in the graph below:

Answer 1

$\bf\mathtt\red{Answer:-}$

Constant = 5 》 For distance

15 》For minutes

Here both time and distance are proportional..

Answer 2

From the given graph as above

(x-15)/(y-5) = (x-30)/(y-10)

(x-15)(y-10) = (x-30)(y-5)

xy - 10x - 15y + 150 = xy - 5x - 30y + 150

- 5x + 15y = 0

-x + 3y = 0

x - 3y = 0
