The table below shows the number of grams of carbohydrates, x, and

the number of Calories, y, of six different foods.

Carbohydrates (x) Calories (y)

8 120

9.5 138

10 147

6 88

7 108

4 62

Which equation best represents the line of best fit for this set of data?

(1) y = 15x (3) y = 0.1x - 0.4

(2) y = 0.07x (4) y = 14.1x + 5.8

equation that best represents the line of the best fit for this set of data is:

1) y = 15x

x y : I divided y by x

8 120 : 120/8 = 15

9.5 138 : 138/9.5 = 14.53 can be rounded up to 15

10 147 : 147/10 = 14.70 can be rounded up to 15

6 88 : 88/6 = 14.67 can be rounded up to 15

7 108 : 108/7 = 15.42 can be rounded down to 15

4 62 : 62/4 = 15.50 can be rounded down to 15

y = 15x

120.00 = 15.00 8.00

142.50 = 15.00 9.50

150.00 = 15.00 10.00

90.00 = 15.00 6.00

105.00 = 15.00 7.00

60.00 = 15.00 4.00
