Oscar and Maria each wrote an equation that they felt represented the proportional relationship between distance in kilometers and distance in miles. One entry in the table paired 152 km with 95 miles. If $$k$$ represents the number of kilometers and $$m$$ represents the number of miles, who wrote the correct equation that would relate kilometers to miles? Explain why.
Sketch a graph that represents the correct proportional relationship between kilometers and miles.
