Question

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

Answer 1

Answer:

$-2\frac{2}{5}$

Step-by-step 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:

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

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

$-slope = \frac{8-(-4)}{4-9}$

$= \frac{12}{-5}$

$= -2\frac{2}{5}$

Therefore, the slope of the line which passes through the points (4,8) and (9,-4) is $-2\frac{2}{5}$.

Answer 2

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

slope of a line =  Y2 - Y1

                            X2 - X1

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

                            9   - 4           5
