Question

5)
If the slope of a line passing through the points Aſk, 2) and B( -6,8) is -6/4
, then k =
A)-6/5
B)-5/6
C)6/5
D)5/6
​

Answer 1

Answer:

For the coordinates given , slope (gradiant) of the line ax+by+c=0 is ( Y-Y1) / (X-X1) = k(here say )

Steps to find -------

(2-8) ÷ {k-(-6)} = -6/4

-6/ (k+6) = -6/4

k+6 = 4

i.e. k = -2
