The analysis of a data set last year produced a line of best fit with equationy = 2.1082 – 0.3818. Data was collected from the same sample this year and produced a line of best fit with equation y= 2.107x + 1.7455. Explain the vertical
change in going from last year's data to this year's data. Show all your work for full credit.

The only number less than 8 that can equal 12 would be 6, 36 is the dividend

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
