Question

The vertices of a triangle are A(3,8) B(-1,2) C(6,-6) find the slope of BC​

Answer 1

Given that,

Find the slope of BC, where B(-1, 2) & C(6, -6)

Let,

$⟹x1 = - 1 \\ ⟹y1 = 2 \\ ⟹x2 = 6 \\ ⟹y2 = - 6$

Formula of slope is

$slope \: = \frac{(y2 - y1)}{(x2 - x1)}$

Substitute the values

$⟹ \frac{ (- 6 - 2)}{(6 - ( - 1))} \\ \\ ⟹ \frac{ - 8}{6 + 1} \\ \\ ⟹ \frac{ - 8}{7}$

∴ Slope of BC is “ -8/7 ”
