Dewi and sheila had some money. if dewi gave sheila $23,she would have 3/5 as much as sheila. if sheila gave dewi $42 , she would have 4/5 as much money as dewi. how much did dewi have?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
