For this case, what you should know is that a linear function has a constant average rate of change, because its slope is constant.
Table number two from left to right represents a linear function.
The line is:
y-yo = m (x-xo)
Where
The slope is:
m = (0 - (- 5)) / (2-1)
m = 5/1
m = 5
The line is:
y-0 = 5 (x-2)
Rewriting:
y = 5x-10
Answer:
Table two from left to right.
The equation is:
y = 5x-10
<span>14-3y=4y
Add 3y to both sides so that the variable y is only on one side.
14=7y
Divide 7 on both sides so that the only thing remaining on the right side is the variable y.
Final Answer: 2=y</span>
Answer:
B (2, 4)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem the constant of proportionality k is given and is equal to

so
The linear equation is given by

That means ----> the y-coordinate is two times the x-coordinate
therefore
The other point is B(2.4)
Because
For x=2, y=4
the y-coordinate is two times the x-coordinate

There are many theories and measurement for the speed of light. It is believed that light travels at 299,792 km per second. In the earlier day philosopher Aristotle believed that light didn't travel but happens instantaneously. Therefore, for Galileo and his assistant to be only 1km apart, I would have to agree with Aristotle theory of light traveling instantaneously.
