Question:

The diagram below shows the graph of a proportional relationship. The plotted point is (6,9) .

What is the unit rate of this graph? Be sure to simplify your answer.

Answer:

The unit rate of this graph is 1.5

Explanation:

The graph shows a proportional relationship and the plotted point is (6,9).

The unit rate of the graph can be determined by the formula,

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=m

Thus, from the graph, the coordinates are (0,0) and (6,9)

Substituting the coordinates in the formula, we have,

\frac{6-0}{9-0} =m

Subtracting, we get,

m=\frac{6}{9} =1.5

Thus, the unit rate of the graph is 1.5
