Y = -4x + 13
y = mx + c ; m = -4 , c = 13
Let m be M1,
(M1)(M2) = -1
-4 (M2) = -1
M2 = 1/4
At P (-1,-2),
y = mx + c ; y = -2 , m = 1/4 , x = -1 , c = ?
-2 = (1/4)(-1) + c
c = - 7/4
Hence , the equation of the line is y = x/4 - 7/4

Answer:
Wheres the question?
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
sin A = opp. /hyp. = CB/AB = 12/ 15 so CB =12 and AB=15
apply Pythagorean Th. for triangle ABC to find AC
AC²= AB²-CB² = 15²-12² = 81; AC = √81=9
tan A = opp./adj. = CB /AC = 12/ 9 = 4/3
