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.

Explanation:

The slope is given by,

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

Now consider the given two points,

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

Therefore,

$\begin{gathered} Slope=\frac{4-7}{1-0} \\ =-\frac{3}{1} \\ =-3 \end{gathered}$

Final Answer:

$Slope=-3$
