Question

.....

Answer 1

for some reason (idk why exactly), excel is spitting out y = 1.0229x - 2018.3 for the trendline...but that's not one of the answer choices

we can rule out the last two because plugging in anything greater than 3 will give a cost much larger than 58.92

So choices C and D are out

Answer 2

notice how 2019 is 21 years after 1998 (since 2019 - 1998 = 21)

So plug in x = 21 and evaluate

y = 1.006x + 26.40

y = 1.006(21) + 26.40

y = 47.526

So the answer is choice A

Answer 3

You research the average cost of a tank of gasoline for a certain type of car for several recent years to look for trends. The table shows your data. What is the equation for a line of best fit? How much would you expect to pay for a tank of gas in the year 2019?

Note: The table below shows the average cost for one tank of gasoline, not one gallon.

(1 pt) y = 1.006x + 26.40; $47.52
(0 pts) y = 1.006x + 26.40; $58.92
(0 pts) y = 26.40x + 1.006; $47.52
(0 pts) y = 26.40x + 1.006; $58.92
