Question

in the lunar eclipse position of sun,earth,moon are (-4,6) (k,-2) and (5,-6) find k​

Answer 1

k =2

during lunar eclipse, all the three lie in a straight line....i.e, they are collinear....

hence.....

slope of (-4,6) & (k,-2) = slope of (-4,6) & (5,-6)

(-2-6)/(k+4) = (-6-6)/(5+4)

-8/(k+4) = -12/9

k+4 = 72/12

k = 2

Answer 2

Answer:

K=2

Step-by-step explanation: on a lunar eclipse the sun, earth,moon lie on same line

Therefore the points are collinear
