Using the point slope form y - y1 = m(x-x1)
m is the slope, because the lines are parallel the slope is identical, so m = -2.
Replace x1 and y1 with the given point and then solve for y:
y - 1 = -2(x-4)
Simplify:
y - 1 = -2x + 8
Add 1 to both sides:
y = -2x +9
Answer:
The temperature dropped 12 degrees over 3 hours. How much did it change each hour?
Step-by-step explanation:
This question (the answer) is asking you to do 12 divided by 3. That would be 12/3 (which is what was in the original question). Also, the temperature dropped, so that would be why it is -12/3

Answer:
1.2 t/m³
Step-by-step explanation:
1 tonne is 1 Mg = 10⁶ g
1 m³ is (100 cm)³ = 10⁶ cm³
The conversion is ...
(1.2 g/cm³) · (1 t)/(10⁶ g) · (10⁶ cm³)/(1 m³)
= 1.2(10⁶)/(10⁶) t/m³
= 1.2 t/m³
__
For this conversion, the numerical value does not change. Megagrams per cubic meter is the same ratio as grams per cubic centimeter.
