The interior temperature of a particular gas oven is determined by its dial setting, which goes from 1 (lowest) to 10 (highest). The relationship between the dial setting N and the corresponding temperature T(N) is linear. When the dial setting is 2, the temperature is 150°C, and when the dial setting is 6, the temperature is 202°C.
Which of the following functions represents the temperature as a function of dial setting?

• T(N) = 13N + 150
• T(N) = 13N + 124
• T(N) = 1/13N + 154
• T(N) = 1/13N + 150
