Scales can be expressed in different ways, as long as they are an equivalent ratio compared to the original scale. Example: 3 inches to 7 feet

Below write to two more equivalent ways to express this scale

Karianne and lucius are analyzing a linear function on a graph. karianne says that unit rate is equal to rate of change, but that slope is calculated differently. lucius says that unit rate, rate of change, and slope are calculated the same way. who is correct? explain your answer.

2(n-1)+4n=2(3n-1)n=0no solutioninfinitely many solutions n= - 4 !

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.
