Question

HURRRY! Keiko and Eric each randomly surveyed people with cell phones. They recorded peoples’ ages (a years) and how many texts they send per day on average (t texts). For their respective data, they each drew a line of best-fit and determined its equation. They then compared equations and made inferences based only on the equations they calculated.

Look at attachment.

Determine whether you agree or disagree, based only on the equations above, with
the inferences drawn below.

Keiko states that she has a higher rate of change than Eric. Agree or Disagree.




Agree

Disagree

Answer 1

Based on the Information shown above , i agree . it has a steeper slope which demonstrates a change in the number of texts based on age .

Answer 2

Explanation:

Agree. Based on the equations above, Keiko's line has a steeper slope than Eric's line, indicating a higher rate of change in the number of texts per day with respect to age.
