To find the equation that relates the number of calories \( y \) Ray burns to the number of minutes \( x \) he walks, you need at least two pieces of information: the format of the relationship (whether it is linear, quadratic, etc.) and any specific data points (e.g., calories burned at specific times).
If we assume that the relationship is linear, which is common for such situations, the general equation would be:
\[ y = mx + b \]
Where:
- \( y \) is the number of calories burned,
- \( x \) is the number of minutes walked,
- \( m \) is the rate of calories burned per minute (the slope), and
- \( b \) is the y-intercept (the number of calories burned when \( x = 0 \)).
If you have specific data points or the slope and intercept, you could substitute those values into the equation. If the relationship is not linear, you may need a different form of the equation, depending on the nature of the relationship.
To provide a more accurate equation, please share any specific data points or details about the graph.
