Tolong nomor 3 ya!!!!

Tolong nomor 3 ya!!!!

S (1, -3p)

x1 = 1

y1 = -3p

D (-4, 2p – 5)

x2 = -4

y2 = 2p – 5

$m = 3$

$frac{y2 - y1}{x2 - x1} = 3$

$frac{2p - 5 - ( - 3p)}{ - 4 - 1} = 3$

$frac{2p - 5 + 3p}{ - 5} = 3$

$frac{5p - 5}{ - 5} = 3$

$frac{5(p - 1)}{ - 5} = 3$

$- (p - 1) = 3$

$- p + 1 = 3$

$- p = 3 - 1$

$- p = 2$

$p = - 2$
