Answer:
A) 60.
Step-by-step explanation:
We have been given a graph of a line and we are asked to find the unit rate for our given line.
Since we know that slope is also known as the unit rate of a function, so let us find slope of our given line.
[tex]\text{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex], where,
[tex]y_2-y_1}[/tex] represents difference between two y-coordinates.
[tex]x_2-x_1}[/tex] represents difference between two x-coordinates of same y-coordinates.
To find the slope we will use points (0,0) and (4,240).
[tex]\text{Slope}=\frac{240-0}{4-0}[/tex]
[tex]\text{Slope}=\frac{240}{4}[/tex]
[tex]\text{Slope}=60[/tex]
Therefore, unit rate of our given graph is 60 and option A is the correct choice.
