the points (15, 10), (25, 20), (30, 22), (40, 32), (55, 53), (60, 55) represent the time, x, it takes 6 people to travel y miles. the scatterplot below represents the situation.

based on the information above, how many miles should a person who drives for 48 minutes expect to travel?
32 miles
42 miles
48 miles
54 miles

Hence, the number of miles a person who drives for 48 minutes expect to travel is:

                               42 miles.

We are given a scatter plot such that the data points:

(15, 10), (25, 20), (30, 22), (40, 32), (55, 53), (60, 55)

are plotted in it.

and we are given a equation of the trend line of the scatter plot as:

where x represents the time and y represents the distance traveled in miles.

Now, we are asked to find the miles a person would drive in 48 minutes.

i.e. we are asked to find the value of y when x=48

Hence, we put x=48 in equation (1) to get:

which is approximately equal to 42

the first one, all those points on the line just make a strait line.
