Assuming that you mean to put n instead of 5, this is demonstrating The Identity Property.
The identity property is the property that states that by adding 0 to a number, you don't change the value. For example, 510 + 0 = 510.
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We find the slope with the given points:

Thus, the line is given by:

We substitute a point to find "b":

Finally, the equation is:

Answer:

Answer:
1.11
Step-by-step explanation:
1.03+0.08=1.11
For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:

Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
