Question

The chart represents a data set’s given values, predicted values (using a line of best fit for the data), and residual values.

A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries 6, 12, 13, 20. The third column is labeled predicted with entries 7, 11, 15, 19. The fourth column is labeled residual with entries negative 1, positive 1, g, h.
Which are the missing residual values?

g = 2 and h = –1
g = 28 and h = 39
g = –2 and h = 1
g = –28 and h = –39

Answer 1

Residual = (given) − (predicted). For x=3: 13 − 15 = −2. For x=4: 20 − 19 = 1.

So g = −2 and h = 1 (third option).
