Answer:
y = 2x + 1
Step-by-step explanation:
Given a point and the slope, we can plug in these values into the equation to find the value of b:
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
Plug b into the equation:
y = 2x + 1
The correct answer is 401.88 cubic inches of water to fill the toys
Solution
Given data
According to Boyle's law, PV = K
The required general equation thus is

Substituting these values we find that the initial pressure is

The initial pressure to the nearest tenth, therefore, is 1.8 atm.
The final answer, therefore, is Option D
