hitunglah kemiringan garis yng melalui titik berikut. a.A(-3, 3) dan B (8, 2) b.P(0, 6) dan Q (-4, -3) c.R(-2,-8) dan S(5,-2) tolong jwab semuanya !

kemiringan = m = y/x

A. m = (2 - 3)/(8 - (-3)) = - 1/11
B. m = (- 3 - 6)/(- 4 - 0) = 9/4
C. m = (- 2 - (- 8)) / (5 - (-2)) = 6/7

Ingat:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

a.
[tex]\displaystyle m=\frac{2-3}{8-(-3)}=\frac{-1}{8+3}=-\frac{1}{11}[/tex]

b.
[tex]\displaystyle m=\frac{-3-6}{-4-0}=\frac{-9}{-4}=\frac{9}{4}[/tex]

c.
[tex]\displaystyle m=\frac{-2-(-8)}{5-(-2)}=\frac{-2+8}{5+2}=\frac{6}{7}[/tex]
