Colleen recorded the price of gas on the first day of each month for several months. She drew a scatter plot and created a linear model. She found the equation of the line of best fit to be y = 0.06x + 1.77, where x is the number of months since she began her study, and y is the price of gas. Using the line of best fit, what will the price of gas be 15 months after Zahra began her study? Enter your answer in the box.

Respuesta :

If the slope is 0.06 then all you would do is multiply that by 15. And then add your y (1.77) which would give you the answer 2.67. 

Answer: Price of gas = 2.67

Explanation:

Linear regression consists of finding the best-fitting straight line through the points. The best-fitting line is called a regression line. regression line and consists of the predicted score on Y for each possible value of X.

Colleen recorded the price and create a linear model.

The equation of the line is y = 0.06x + 1.77

After fifteen months we need to find the price of gas.

Here value of x = 15 (because x represent the number of months)

and y represents the gas's price.

Now we put x = 15 in given equation y = .06x+1.77

y = 0.06(15) + 1.77

y = 0.9 + 1.77

y = 2.67

So, price of gas is 2.67

Final answer.

I hope its help to you.
