Please EXPLAIN how to determine the constant of proportionality from a graph, a table, and an equation. Make sure to explain in depth.

(Please please help me with this I know how to do it I just don't know how to explain it)

look a the sides they are perpendicular

5+2x=a

asdasdsaadsaddsasds

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

answer: it is 8

step-by-step explanation:

you know why its 8
