The distance a train travels is proportional to time. in 4 hours, the train travels 380 kilometers. the relationship between distance and time can be represented as y= ox, where x is the time, in hours, and y is the distance, in kilometers. what is the value of k for this train ?

Which equation represents the line that passes through the points and (4, 10) and (2, 7)? y = 3/2x - 11y = 3/2x +4y = - 3/2x + 19y = - 3/2x + 16
