What is the constant of variation, k, of the direct variation, y = for, through (5,8)?

Step-by-step explanation:

The constant of direction variation givens a proportion that is maintained by both x and y values for all points of a line that it passes through.

Usually represented with the variable , it is given by:

for coordinates (x, y).

This relationship can be written as which is also the layout for a proportional relationship.

Since coordinates are written (x, y), for point (5, 8), substitute to get the constant of variation:

8/5

Step-by-step explanation:

Given that y varies directly with x , therefore ,

Let k be the constant . Therefore ,

When the point is (5,8) ,

Hence the constant of variation is 8/5.

the answer is 28
