The conversion of degrees Celsius to degrees Fahrenheit can be represented by a linear relationship.

The graph shows the linear relationship between y, the temperature in degrees Fahrenheit, and x, the temperature in degrees Celsius from the freezing point of water.
Which equation best represents this situation?

The equation that best represents this situation is:

y = 1.8x + 32

This equation indicates that the temperature in degrees Fahrenheit (y) is equal to 1.8 times the temperature in degrees Celsius (x), plus 32. This equation accurately converts degrees Celsius to degrees Fahrenheit using a linear relationship.
