What is the constant of proportionality in the equation y =5/4x

5/4

Step-by-step explanation:

Given the equation y = 5/4x this relationship is an inverse proportionality i.e the y variable is inversely proportional to x.

Mathematically y = k/x where k is the proportionality constant.

Comparing y = 5/4x with y = k/x, the constant of proportionality k in he function y = 5/4x is 5/4

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
