The price of the house is originally listed at 115,000. The owners are having a hard time selling it and decide to reduce the price to 103,500. What is the percentage decrease of the price of the house ?

percentage of decrease in price of house=103,500/115,000×100%=90%

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.
