Question

Find the slope:X Y0 71 42 13 -2

Answer 1

Given:

X Y

0 7

1 4

2 1

3 -2

Required:

To find the slope.

Step-by-step explanation:

The slope is given by,

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

Now consider the given two points,

`\begin{gathered} (x_1,y_1)=(0,7) \\ (x_2,y_2)=(1,4) \end{gathered}`

Therefore,

`\begin{gathered} Slope=(4-7)/(1-0) \\ =-(3)/(1) \\ =-3 \end{gathered}`

Final Answer:

`Slope=-3`
