A graph of Fahrenheit temperature versus Celsius temperature is a straight line, whose intercept is _____.

Correct option is A

F = $$\frac{9}{5}C + 32$$​​

This is a linear equation of the form y = mx + c, where:

• F (Fahrenheit) is plotted on the y-axis
• C (Celsius) is on the x-axis
• Slope (m) is 9/5
• Intercept (c) is 32°F

So, the intercept of the graph on the Fahrenheit axis (when Celsius is 0) is:

F = $$\frac{9}{5}(0) + 32 = 32^\circ F$$​​

• Conversion Formula: F =$$\frac{9}{5}C + 32$$​​
• Freezing point of water: 0°C = 32°F
• Boiling point of water: 100°C = 212°F
• The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit.
  
• The graph is a straight line, indicating a linear relationship.
