I don't understand. What are the values given? Are they values of an x,y plot?
If you plot them they are a straight line with y =6x - 2.9 but I don't know what you mean by when x=3 and y = 4?
The unit rate would be 48.5 miles per hour because you would just divide 194 and 4 and get the ratio of 48.5:1
Answer: your answer should be 0.51
Some people are saying it's 0.04 but that is the wrong answer.
do u have to use the exact same number for all the substitutions?
