Question

Donald swan 6 miles at a constant pace.the graph below showed the pace at which he Donald traveled

Answer 1

As per given by the question,

The are given that a line on a grapg.

Now,

For the slope of the given graph ;

According to the graph, Donald swan 6 miles at a constant pace .

So,

From the formula of slope,

`m=(y_2-y_1)/(x_2-x_1)`

Here, point from the graph is,

`(x_1,x_2)=(2.5,5),and(y_1,y_2)=(6,\text{ 3)}`

Now,

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=\frac{6_{}-3_{}}{5_{}-2.5_{}} \\ m=(3)/(2.5) \\ m=1.2 \end{gathered}`

So, the value of slope is 1.2.

Hence, the option d is correct.
