Question

Find the slope of the line containing the pair of points (4,8), (9,-4)

Answer 1

The given points are (4,8) & (9,-4)

slope of a line = Y2 - Y1

X2 - X1

====> (-4) - 8 = -12

9 - 4 5

Answer 2

`-2(2)/(5)`

Explanation:

We have a line which passes through the points (4,8) and (9,-4). So with the help of these pair of points, we can find the slope of the line.

We know that:

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

So putting in the values of the given coordinates to get:

`-slope = (8-(-4))/(4-9)`

`= (12)/(-5)`

`= -2(2)/(5)`

Therefore, the slope of the line which passes through the points (4,8) and (9,-4) is
`-2(2)/(5)`.
