The temperature reading taken using Centigrade and Fahrenheit thermometers are plotted on a graph -?C along X-axis, ?F along Y-axis. The shape of graph would be

• A. Straight line cutting an intercept on the negative Y-axis
• B. Straight line cutting an intercept on the positive Y-axis
• C. Straight line cutting an intercept on the negative X-axis
• D. 273?C
• E. Straight line cutting an intercept on the positive X-axis
