Answer:
y = 5x - 7
Step-by-step explanation:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (-12 - 3) / (-1 - 2)
= (-12 - 3) / (-1 - 2)
= -15 / -3
m = 5
y-intercept using slope above and anyone point, let's use (-1, -12):
y = mx + b
-12 = 5(-1) + b
-12 = -5 + b
b = -7
Equation of line using m and b from above:
y = mx + b
y = 5x - 7
Answer:
6 1 / 24
Step-by-step explanation:
in 1 hour - 5 / 6 tons of dust
Total dust = 7 1 / 4 = 29 / 4
1 ----- 5 / 6
x ----- 29 / 4
x = (29 / 4 ) * (5 / 6)
x = 145 / 24
x = 6 1 / 24
You would factor 8x - 4 as 4 ( 2x - 1)
