Question

find K if R(1,-1), S(-2,K) and slope of line RS is -2​

Answer 1

Answer:

k-(-1)/-2-(1)=-2

k+1/-3=-2

k+1=6

k=5

plz mark it as brainliest answer

Answer 2

Step-by-step explanation:

to find k..,

we use,

the formula

y2 - y1/X2 - X1 = slope of line

k - (-1) / -2 (1) = -2

k + 1 / -2 = 2

now,

k + 1 = 2 (-2)

k + 1 = -4

and, k = - 4 - 1

so, the value of 'k' = -5
