<em>Please refer to my Answer from this question to know more about the slope of a line: <u>brainly.com/question/24599351</u></em>
In graph 9, we can see a line that is perfectly horizontal. Graphs of lines that are horizontal has a slope of, .
If you want we can still solve for the slope of the line in graph 9, without acknowledging that the line is horizontal.
In graph 9, we can see that the points, and
, is on the line. These can be our points
and
.
In graph 10, we can see that the points, and
, is on the line. These can be our points
and
.

Let's firstly convert the mixed fraction to "improper" and then proceed,
The sum of ( x +
) + (
x -
) is
x +
Step-by-step explanation:
To add or subtract 2 fractions, they must have same denominators, if they not do that
- Find the Lowest common multiple of the two denominators (LCM)
- Replace each denominator by it
- Divide The LCM by each denominator and multiply the numerator of each fraction by its quotient
∵ ( x +
) + (
x -
)
- Let us start with adding the like terms
∴ ( x +
) + (
x -
) = (
∵ ( x +
x ) have same denominators, then we can add them
∴ ( x +
x ) =
x
∵ ( -
) do not have the same denominators, then we must find
LCM of 8 and 4
- The LCM of 8 and 4 is 8 because 8 is the first common multiple
of 8 and 4
∵ LCM of 8 and 4 is 8
- Divide 8 by the denominator 4
∵ 8 ÷ 4 = 2
- Multiply the numerator of the fraction by 2
∴
∴ ( -
) = (
-
) =
∴ ( x +
) + (
x -
) =
x +
The sum of ( x +
) + (
x -
) is
x +
