The greenhouse temperatures at certain times are shown in the table. The greenhouse maintains temperatures between 65 degrees F and 85 degrees F. Suppose the temperature increases at a constant rate. Create a graph of the time and temperatures at each hour from 1:00 pm to 8:00 pm. Is the relationship proportional? The answer will be either 1 for proportional or 2 for not proportional. * |

Answer» ong>Given : The greenhouse maintains temperatures between 65 degrees F and 85 degrees F. Suppose the temperature increases at a constant rate To Find : Is the relationship PROPORTIONAL Solution: Properties of proportional relation : A proportional relationship must graph as a line graph of a proportional relationship must pass through (0, 0). Each point (or PAIR) in a proportional relationship must share the same ratio. y = mx is proportional relation Time temperature 1 66 6 78.5 8 83.5 The greenhouse maintains temperatures between 65 degrees F and 85 degrees F the temperature increases at a constant rate Hence y = 2.5x + 63.5 is the graph hence c ≠ 0 at time 0 temperature is not zero Hence relationship is not proportional Learn More: Which statement about proportional RELATIONSHIPS is false?
