The expression above becomes . On taking the difference;
The final expression gives the right answer
the equation framed in the form of y=kx is and , x as a function of y
.
<u>Step-by-step explanation:</u>
Here we have , The amount Lin's sister earns at her part-time job is proportional to the number of hours she works. She earns $9.60 per hour. We need to find an equation in the form y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns.Is y a function of x . Also , Write an equation describing x as a function of y . Let's find out:
Here , Lin's sister earns $9.60 per hour . Let x represents the hours she works and y represents the dollars she earns . So , According to question following is the equation framed in the form of y=kx :
⇒
Yes, y is a function of x , as a straight line with a slope of 9.6
Now , x as a function of y :
⇒
⇒
Therefore , the equation framed in the form of y=kx is and , x as a function of y
.
