Identify the unit rate in the graph.

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let's find the unit rate (r) ~
[tex]\qquad \tt \dashrightarrow \:r = \dfrac{y 2 - y1}{x2 - x1} [/tex]
[tex]\qquad \tt \dashrightarrow \:r = \dfrac{50 - 0}{1 - 0} [/tex]
[tex]\qquad \tt \dashrightarrow \:r = {50 }{} \: mph[/tex]
