Question

Find the slope of line joining the pionts (3, -2) and (-1, 4)​

Answer 1

Step-by-step explanation:

Slope of a line (m) joining two points (h, k) and (x, y) is given by

$m = \frac{y - k}{x - h}$

Here the points are (3,-2) and (-1,4)

so, x=-1, y=4, h=3, k=-2

Put these values in above equation

$m = \frac{4 - ( - 2)}{( - 1) - 3}$

$m = \frac{4 + 2}{ - 1 - 3}$

$m = \frac{ - 6}{4}$

$m = \frac{ - 3}{2}$

so the slope is -3/2
