tolong jawab 1 dan 2 secepatnya!please

1. Gradien = m
y = mx + b

a.) y = -5x + 4
m = -5

b.) 2y = 3x - 1
y = 3/2 x - 1/2
m = 3/2

c.) 3x + 4y - 5 = 0
4y = -3x + 5
y = -3/4 x + 5/4
m = -3/4

d.) -x + 6y = 4
6y = x + 4
y = 1/6 x + 4/6
m= 1/6


2. gradien = m
gradien = Y2 - Y1 / X2 - X1

a.) A(6,7) B(-5,3)

m = 3 - 7 / -5 - 6
m = -4 / -11
m = 4/11

b.) P(2,-1) Q(-4,-2)
m = -2 - (-1) / -4-2
m = -2 + 1 / -6
m = -1 / -6
m = 1/6
