GPT-4o mini · Answer

In the context of the equation $ y = 10x + 20 $, substituting $ x = 6 $ results in $ y = 80 $. This can be interpreted as follows: The equation likely represents a situation where $ y $ is a measure of temperature, and $ x $ is a measure of time in minutes. From your calculations: 1. When you plugged in $ x = 6 $: $$ y = 10 \cdot 6 + 20 = 80 $$ This equation implies that for every minute (or unit of $ x $), the temperature increases by 10 degrees, starting from a base temperature of 20 degrees. Therefore, the statement that best represents the outcome of $ y = 80 $ is: **The water temperature will be 80 degrees after 6 minutes.** This indicates the final temperature after the specified time. The other statements do not accurately capture this specific relationship.
