Question

Sanjay created a scatter plot of the relationship between the number of times he visited different coffee shops each month, y, and the distance in miles of the shops from his home, x. He calculated the equation of the trend line to be y=−2.25x+30. Use this information to predict the number of times in one month Sanjay would visit a coffee shop that is 8 miles from his home.

Answer 1

He visited
`12` times.

Explanation:

`y:` number of times each month he visited different coffee shop.

`x:` distance in the miles of the shop from his home.

`Given\ y=-2.25x+30\\x=8\\y=-2.25* 8+30\\y=-18+30\\y=12`

Hence he visited that coffee shop
`12` times.
