In El Yunque rainforest in Puerto Rico, 116 male coqui frogs were studied, Biologists found that the call duration of the coquis is linearly related to their altitude in the rainforest. When the coquis call for 350ms, they are at about 0.2km altitude. When they call for 430ms, they are at about 0.8km altitude. (a) Find the slope of the line connecting the two points (0.2, 350) and (0.8, 430). Round to the nearest tenth as needed.

(b) Using complete sentences, interpret the slope of the line found in part (1a).
