Answer
If you didn't it there wouldn't be an easy method to do the problem.Having the same denominator is the easiest method and is pretty basic.If you didn't have a common denominator such as:5/8 + 7/6, it would be virtually impossible to solve.
Step-by-step explanation:
Answer:
y=-x+8
Step-by-step explanation:
First distribute the negative
2y=(-x+4)2+8
then you would multiply the (-x+4) by the two
2y=-2x+8+8
then you would combined like terms
2y=-2x+16
then you would divide both sides by 2
y=-x+8

Any line can be graphed using two points. Select two
x
values, and plug them into the equation to find the corresponding
y
values.
Choose
0
to substitute in for
x
to find the ordered pair.
y
=
9
Choose
1
to substitute in for
x
to find the ordered pair.
y
=
12
Create a table of the
x
and
y
values.
x
