Add the top then add the bottom
Answer:

To find this you must find the slope first:

which is, after performing some calculating is -2.
Next you need to set up your eqaution:

when you set it up, and substitute the variables for your slope and points you should get this:


add 2 to both sides

subtract y from both sides
The original price is 30$ because we know that the new price is worth 60% of the old price. We can set up an equation to model this: 0.60x = 18. Dividing both side by 0.60 gives us an original value of 30. If you take 40% off of 30 you get 18 — allowing us to check our work.
