Question

The question is : Find the constant of proportonially. Constant Of proportionally=y/x for any point of the line

Answer 1

First it is needed to find the slope with the following equation

`m=(y2-y1)/(x2-x1)`

We take two points of the line. (10,50) and (3,15)

Then you substitute them on the equation

`(50-15)/(10-3)=(35)/(7)=5`

The answer would be 5 gal/min
