Interpret intercepts and starting values in contextual linear situations.

Match the same special value across forms

Problem

A candle burns down at a constant rate. Identify every representation that shows an initial height of \(18~\text{centimeters}\).

A. When \(\text{time}~=~0~\text{minutes}\), \(\text{height}~=~18~\text{centimeters}\)
B. The graph includes the point \((18,~0)\)
C. The rule \(h~=~18~-~2t\)
D. After \(18~\text{minutes}\), the candle height is \(0~\text{centimeters}\)
E. A table begins with \(t~=~0,~h~=~18\); then \(t~=~1,~h~=~16\)
F. The statement, “The candle loses \(18~\text{centimeters}~\text{each}~\text{minute}\).”
G. The statement, “Before any time has passed, the candle is \(18~\text{centimeters}\) tall.”
