Answer:
slope = -2/3; y-intercept is point (0, -6)
Step-by-step explanation:
y = -6 - 2/3 x
y = -2/3 x - 6
y = mx + b
m = slope = -2/3
b = y-intercept = -6
Answer: slope = -2/3; y-intercept is point (0, -6)
<span>x in (-oo:+oo)
(x+20)/2 = 3*x // - 3*x
(x+20)/2-(3*x) = 0
(x+20)/2-3*x = 0
(x+20)/2+(-3*2*x)/2 = 0
x-3*2*x+20 = 0
20-5*x = 0
(20-5*x)/2 = 0
(20-5*x)/2 = 0 // * 2
20-5*x = 0
20-5*x = 0 // - 20
-5*x = -20 // : -5
x = -20/(-5)
x = 4 so x= 4</span>
