Answer
newtons first law says that when an equal force is applied to force it causes it to accelerate
Explanation:
Answer:
5.25%
Explanation:
From the question given above, the following data were obtained:
Accepted value = 238857 miles
Measured value = 226316 miles
Percentage error =.?
Next, we shall determine the absolute error. This can be obtained as follow:
Accepted value = 238857 miles
Measured value = 226316 miles
Absolute Error =?
Absolute Error = |Measured – Accepted|
Absolute Error = |226316 – 238857|
Absolute Error = 12541
Finally, we shall determine the percentage error. This can be obtained as follow:
Accepted value = 238857 miles
Absolute Error = 12541
Percentage error =.?
Percentage error = absolute error / accepted value × 100
Percentage error
= 12541 / 238857 × 100
= 1254100 / 238857
= 5.25%
Therefore, the percentage error is 5.25%.

Though it is easier to use the origin as one of the points to find the rise over the run, doing the question the more general way will help you with lines that do not go through the origin.
So pick any other two points.
P1(6 , 0.60)
P2(8 , 1.20)
Rise / Run = (y2 - y1)/(x2 - x1)
y2 = 1.20
y1 = 0.90
x2 = 8
x1 = 6
Rise over Run = (1.2 - 0.9) / (8 - 6)
Rise over run = 0.3 / 2
Technically stated in language, this is the answer. For every 2 pencils the cost goes up 0.3 cents. Carpenters would say it this way.
However in physics it can also be expressed as 0.15 dollars per pencil which is the cost per pencil.
=========================
Just to show that you will get the same answer using the origin you can do it this way.
y2 = 0.6
y1 = 0
x2 = 4
x1 = 0
rise over run = (0.6 - 0)/ (4 - 0) = 0.6/4 = 0.15 / 1
The height isn’t a factor.
The gravitational force is the same no matter the height...
So W=mg
20 x 9.81 = 196.2 N
