For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have two points through which the line passes:
We found the slope:
Thus, the equation is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
- <em>combined mass in scientific notation can be written as</em> 97.2×
kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x kg )
Mercury= (3.3x kilograms)
Then we add together
(6.42x )+ (3.3x
) kilograms.
= 9.45 × kilograms
Therefore, combined mass in scientific notation can be written as 97.2× kg
