Residents in a city are charged for water usage every three months. The water bill is computed from a common fee,

along with the amount of water the customers use. The last waler bills for 40 residents from two different

neighborhoods are shown in the histograms below.

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.

25% is the answer

a)(x-2)^2+(y-1)^2=9
