Answer:
1. Y=2x
2. X represents the number of days for sale and Y represents the number of times the house has been viewed
3. If the house was on sale for 40 days it would have been viewed 80 times.
4. When the house is viewed for 70 days it will be on sale 35 times.
Explanation:
1. Rise over run. You go up 10 and to the side by 5. 10/5 is 2 .
2. Under the X and Y lines it clearly has a small title of what X and Y represent. All you had to do was look at it.
3. 40 is the days on sale and since the slope is 2 you just multiply 40 times 2 and you get 80.
4. If the house was viewed 70 times since it is the y you divide it by the slope of 2. 70 divided by 2 is 35.
