1. what is the constant of proportionality, k,

of kevin's wage? greg's? savannah's?

Part a) The constant of proportionality of Kevin's wage is

Part b) The constant of proportionality of Greg's wage is

Part c) The constant of proportionality of Savannah's wage is

Step-by-step explanation:

See the attached figure to better understand the problem

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

To find out the constant of proportionality k , divide the variable y (total earned) by the variable x (number of hours)

Kevin's wage

Take any point from the table

I take the point (2,16.50)

Greg's wage

Take any point from the table

I take the point (3,27.00)

Savannah's wage

Take any point from the table

I take the point (2,19.00)

99

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
