Question

I was able to get to 9 from problem 3constant of proportionality

Answer 1

The constant of proportionality of the graph can also be called the slope.

To find the constant of proportionality, apply the slope formula:

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

Take the points on the like:

(x1, y1) ==> (-5, -1)

(x2, y2) ==> (5, 1)

Substitute values into the slope formula:

`\begin{gathered} m=(1-(-1))/(5-(-5)) \\ \\ m=(1+1)/(5+5) \\ \\ m=(2)/(10) \\ \\ m=(1)/(5) \end{gathered}`

Therefore, the constant of proportionality of the line is ⅕

ANSWER:

`(1)/(5)`
