Question

Identify the unit rate in the graph     .
A) 60
 B) 120
 C) 180
 D) 240

Answer 1

The unit rate of the graph is A) 60. This is because the graph goes up 60 miles for every hour. Hope this helps!

Answer 2

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.

$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}$, where,

$y_2-y_1}$ represents difference between two y-coordinates.

$x_2-x_1}$ represents difference between two x-coordinates of same y-coordinates.

To find the slope we will use points (0,0) and (4,240).

$\text{Slope}=\frac{240-0}{4-0}$

$\text{Slope}=\frac{240}{4}$

$\text{Slope}=60$

Therefore, unit rate of our given graph is 60 and option A is the correct choice.
